Roaming Profiles are feared by some, hated by a few, loved by many, and a Godsend for some administrators.
Roaming Profiles allow an administrator to make available a consistent user desktop as the user moves from one machine to another. This chapter provides much information regarding how to configure and manage Roaming Profiles.
While Roaming Profiles might sound like nirvana to some, they are a real and tangible problem to others. In particular, users of mobile computing tools, where often there may not be a sustained network connection, are often better served by purely Local Profiles. This chapter provides information to help the Samba administrator to deal with those situations also.
Roaming profiles support is different for Win9x / Me and Windows NT4/200x.
Before discussing how to configure roaming profiles, it is useful to see how Windows 9x / Me and Windows NT4/200x clients implement these features.
Windows 9x / Me clients send a NetUserGetInfo request to the server to get the user's profiles location. However, the response does not have room for a separate profiles location field, only the user's home share. This means that Win9X/Me profiles are restricted to being stored in the user's home directory.
Windows NT4/200x clients send a NetSAMLogon RPC request, which contains many fields, including a separate field for the location of the user's profiles.
This section documents how to configure Samba for MS Windows client profile support.
To support Windowns NT4/200x clients, in the [global] section of smb.conf set the following (for example):
logon path = \\profileserver\profileshare\profilepath\%U\moreprofilepath
logon path = \\%L\Profiles\%u
The default for this option is \\%N\%U\profile, namely \\sambaserver\username\profile. The \\N%\%U service is created automatically by the [homes] service. If you are using a samba server for the profiles, you _must_ make the share specified in the logon path browseable. Please refer to the man page for smb.conf in respect of the different symantics of %L and %N, as well as %U and %u.
MS Windows NT/2K clients at times do not disconnect a connection to a server between logons. It is recommended to NOT use the homes meta-service name as part of the profile share path.
To support Windows 9x / Me clients, you must use the logon home parameter. Samba has now been fixed so that net use /home now works as well, and it, too, relies on the logon home parameter.
By using the logon home parameter, you are restricted to putting Win9x / Me profiles in the user's home directory. But wait! There is a trick you can use. If you set the following in the [global] section of your smb.conf file:
logon home = \\%L\%U\.profiles
then your Windows 9x / Me clients will dutifully put their clients in a subdirectory of your home directory called .profiles (thus making them hidden).
Not only that, but net use /home will also work, because of a feature in Windows 9x / Me. It removes any directory stuff off the end of the home directory area and only uses the server and share portion. That is, it looks like you specified \\%L\%U for logon home.
You can support profiles for both Win9X and WinNT clients by setting both the logon home and logon path parameters. For example:
logon home = \\%L\%u\.profiles logon path = \\%L\profiles\%u
A question often asked is “How may I enforce use of local profiles?” or “How do I disable Roaming Profiles?”
There are three ways of doing this:
logon home = logon path =
Local Computer Policy\ Computer Configuration\ Administrative Templates\ System\ User Profiles\ Disable: Only Allow Local User Profiles Disable: Prevent Roaming Profile Change from Propogating to the Server
From the start menu right click on the My Computer icon, select , click on the User Profiles tab, select the profile you wish to change from Roaming type to Local, click .
Consult the MS Windows registry guide for your particular MS Windows version for more information about which registry keys to change to enforce use of only local user profiles.
The specifics of how to convert a local profile to a roaming profile, or a roaming profile to a local one vary according to the version of MS Windows you are running. Consult the Microsoft MS Windows Resource Kit for your version of Windows for specific information.
When a user first logs in on Windows 9X, the file user.DAT is created, as are folders Start Menu, Desktop, Programs and Nethood. These directories and their contents will be merged with the local versions stored in c:\windows\profiles\username on subsequent logins, taking the most recent from each. You will need to use the [global] options preserve case = yes, short preserve case = yes and case sensitive = no in order to maintain capital letters in shortcuts in any of the profile folders.
The user.DAT file contains all the user's preferences. If you wish to enforce a set of preferences, rename their user.DAT file to user.MAN, and deny them write access to this file.
On the Windows 9x / Me machine, go to -> and select the User Profiles tab. Select the required level of roaming preferences. Press , but do _not_ allow the computer to reboot.
On the Windows 9x / Me machine, go to -> -> -> Preferences. Select Log on to NT Domain. Then, ensure that the Primary Logon is Client for Microsoft Networks. Press , and this time allow the computer to reboot.
Under Windows 9x / Me Profiles are downloaded from the Primary Logon. If you have the Primary Logon as 'Client for Novell Networks', then the profiles and logon script will be downloaded from your Novell Server. If you have the Primary Logon as 'Windows Logon', then the profiles will be loaded from the local machine - a bit against the concept of roaming profiles, it would seem!
You will now find that the Microsoft Networks Login box contains [user, password, domain] instead of just [user, password]. Type in the samba server's domain name (or any other domain known to exist, but bear in mind that the user will be authenticated against this domain and profiles downloaded from it, if that domain logon server supports it), user name and user's password.
Once the user has been successfully validated, the Windows 9x / Me machine will inform you that The user has not logged on before' and asks you if you wish to save the user's preferences? Select .
Once the Windows 9x / Me client comes up with the desktop, you should be able to examine the contents of the directory specified in the logon path on the samba server and verify that the Desktop, Start Menu, Programs and Nethood folders have been created.
These folders will be cached locally on the client, and updated when the user logs off (if you haven't made them read-only by then). You will find that if the user creates further folders or short-cuts, that the client will merge the profile contents downloaded with the contents of the profile directory already on the local client, taking the newest folders and short-cuts from each set.
If you have made the folders / files read-only on the samba server, then you will get errors from the Windows 9x / Me machine on logon and logout, as it attempts to merge the local and the remote profile. Basically, if you have any errors reported by the Windows 9x / Me machine, check the Unix file permissions and ownership rights on the profile directory contents, on the samba server.
If you have problems creating user profiles, you can reset the user's local desktop cache, as shown below. When this user then next logs in, they will be told that they are logging in "for the first time".
Before deleting the contents of the directory listed in the ProfilePath (this is likely to be c:\windows\profiles\username), ask them if they have any important files stored on their desktop or in their start menu. Delete the contents of the directory ProfilePath (making a backup if any of the files are needed).
This will have the effect of removing the local (read-only hidden system file) user.DAT in their profile directory, as well as the local "desktop", "nethood", "start menu" and "programs" folders.
instead of logging in under the [user, password, domain] dialog, press .
run the regedit.exe program, and look in:
HKEY_LOCAL_MACHINE\Windows\CurrentVersion\ProfileList
you will find an entry, for each user, of ProfilePath. Note the contents of this key (likely to be c:\windows\profiles\username), then delete the key ProfilePath for the required user.
[Exit the registry editor].
search for the user's .PWL password-caching file in the c:\windows directory, and delete it.
log off the windows 9x / Me client.
check the contents of the profile path (see logon path described above), and delete the user.DAT or user.MAN file for the user, making a backup if required.
If all else fails, increase samba's debug log levels to between 3 and 10, and / or run a packet trace program such as ethereal or netmon.exe, and look for error messages.
If you have access to an Windows NT4/200x server, then first set up roaming profiles and / or netlogons on the Windows NT4/200x server. Make a packet trace, or examine the example packet traces provided with Windows NT4/200x server, and see what the differences are with the equivalent samba trace.
When a user first logs in to a Windows NT Workstation, the profile NTuser.DAT is created. The profile location can be now specified through the logon path parameter.
There is a parameter that is now available for use with NT Profiles: logon drive. This should be set to H: or any other drive, and should be used in conjunction with the new "logon home" parameter.
The entry for the NT4 profile is a _directory_ not a file. The NT help on profiles mentions that a directory is also created with a .PDS extension. The user, while logging in, must have write permission to create the full profile path (and the folder with the .PDS extension for those situations where it might be created.)
In the profile directory, Windows NT4 creates more folders than Windows 9x / Me. It creates Application Data and others, as well as Desktop, Nethood, Start Menu and Programs. The profile itself is stored in a file NTuser.DAT. Nothing appears to be stored in the .PDS directory, and its purpose is currently unknown.
You can use the System Control Panel to copy a local profile onto a samba server (see NT Help on profiles: it is also capable of firing up the correct location in the System Control Panel for you). The NT Help file also mentions that renaming NTuser.DAT to NTuser.MAN turns a profile into a mandatory one.
The case of the profile is significant. The file must be called NTuser.DAT or, for a mandatory profile, NTuser.MAN.
You must first convert the profile from a local profile to a domain profile on the MS Windows workstation as follows:
Log on as the LOCAL workstation administrator.
Right click on the My Computer Icon, select
Click on the User Profiles tab
Select the profile you wish to convert (click on it once)
Click on the button
In the Permitted to use box, click on the button.
Click on the 'Look in" area that lists the machine name, when you click here it will open up a selection box. Click on the domain to which the profile must be accessible.
You will need to log on if a logon box opens up. Eg: In the connect as: MIDEARTH\root, password: mypassword.
To make the profile capable of being used by anyone select 'Everyone'
Click . The Selection box will close.
Now click on the button to create the profile in the path you nominated.
Done. You now have a profile that can be editted using the samba-3.0.0 profiles tool.
Under NT/2K the use of mandotory profiles forces the use of MS Exchange storage of mail data. That keeps desktop profiles usable.
This is a security check new to Windows XP (or maybe only Windows XP service pack 1). It can be disabled via a group policy in Active Directory. The policy is:
Computer Configuration\Administrative Templates\System\User Profiles\Do not check for user ownership of Roaming Profile Folders
...and it should be set to Enabled. Does the new version of samba have an Active Directory analogue? If so, then you may be able to set the policy through this.
If you cannot set group policies in samba, then you may be able to set the policy locally on each machine. If you want to try this, then do the following (N.B. I don't know for sure that this will work in the same way as a domain group policy):
On the XP workstation log in with an Administrator account.
Click: ,
Type: mmc
Click:
A Microsoft Management Console should appear.
Click: , ,
Double-Click: Group Policy
Click: ,
Click:
In the "Console Root" window:
Expand: Local Computer Policy, Computer Configuration, Administrative Templates, System, User Profiles
Double-Click: Do not check for user ownership of Roaming Profile Folders
Select: Enabled
Click:
Close the whole console. You do not need to save the settings (this refers to the console settings rather than the policies you have changed).
Reboot
Sharing of desktop profiles between Windows versions is NOT recommended. Desktop profiles are an evolving phenomenon and profiles for later versions of MS Windows clients add features that may interfere with earlier versions of MS Windows clients. Probably the more salient reason to NOT mix profiles is that when logging off an earlier version of MS Windows the older format of profile contents may overwrite information that belongs to the newer version resulting in loss of profile information content when that user logs on again with the newer version of MS Windows.
If you then want to share the same Start Menu / Desktop with W9x/Me, you will need to specify a common location for the profiles. The smb.conf parameters that need to be common are logon path and logon home.
If you have this set up correctly, you will find separate user.DAT and NTuser.DAT files in the same profile directory.
There is nothing to stop you specifying any path that you like for the location of users' profiles. Therefore, you could specify that the profile be stored on a samba server, or any other SMB server, as long as that SMB server supports encrypted passwords.
Unfortunately, the Resource Kit information is specific to the version of MS Windows NT4/200x. The correct resource kit is required for each platform.
Here is a quick guide:
On your NT4 Domain Controller, right click on My Computer, then select the tab labelled User Profiles.
Select a user profile you want to migrate and click on it.
I am using the term "migrate" lossely. You can copy a profile to create a group profile. You can give the user 'Everyone' rights to the profile you copy this to. That is what you need to do, since your samba domain is not a member of a trust relationship with your NT4 PDC.
Click the button.
In the box labelled Copy Profile to add your new path, eg: c:\temp\foobar
Click on the button in the Permitted to use box.
Click on the group 'Everyone' and then click . This closes the 'choose user' box.
Now click .
Follow the above for every profile you need to migrate.
You should obtain the SID of your NT4 domain. You can use smbpasswd to do this. Read the man page.
With Samba-3.0.0 alpha code you can import all you NT4 domain accounts using the net samsync method. This way you can retain your profile settings as well as all your users.
The W2K professional resource kit has moveuser.exe. moveuser.exe changes the security of a profile from one user to another. This allows the account domain to change, and/or the user name to change.
You can identify the SID by using GetSID.exe from the Windows NT Server 4.0 Resource Kit.
Windows NT 4.0 stores the local profile information in the registry under the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
Under the ProfileList key, there will be subkeys named with the SIDs of the users who have logged on to this computer. (To find the profile information for the user whose locally cached profile you want to move, find the SID for the user with the GetSID.exe utility.) Inside of the appropriate user's subkey, you will see a string value named ProfileImagePath.
A Mandatory Profile is a profile that the user does NOT have the ability to overwrite. During the user's session it may be possible to change the desktop environment, but as the user logs out all changes made will be lost. If it is desired to NOT allow the user any ability to change the desktop environment then this must be done through policy settings. See previous chapter.
Under NO circumstances should the profile directory (or it's contents) be made read-only as this may render the profile un-usable.
For MS Windows NT4/200x/XP the above method can be used to create mandatory profiles also. To convert a group profile into a mandatory profile simply locate the NTUser.DAT file in the copied profile and rename it to NTUser.MAN.
For MS Windows 9x / Me it is the User.DAT file that must be renamed to User.MAN to affect a mandatory profile.
Most organisations are arranged into departments. There is a nice benenfit in this fact since usually most users in a department will require the same desktop applications and the same desktop layout. MS Windows NT4/200x/XP will allow the use of Group Profiles. A Group Profile is a profile that is created firstly using a template (example) user. Then using the profile migration tool (see above) the profile is assigned access rights for the user group that needs to be given access to the group profile.
The next step is rather important. Please note: Instead of assigning a group profile to users (ie: Using User Manager) on a "per user" basis, the group itself is assigned the now modified profile.
Be careful with group profiles, if the user who is a member of a group also has a personal profile, then the result will be a fusion (merge) of the two.
MS Windows 9x / Me and NT4/200x/XP will use a default profile for any user for whom a profile does not already exist. Armed with a knowledge of where the default profile is located on the Windows workstation, and knowing which registry keys affect the path from which the default profile is created, it is possible to modify the default profile to one that has been optimised for the site. This has significant administrative advantages.
To enable default per use profiles in Windows 9x / Me you can either use the Windows 98 System Policy Editor or change the registry directly.
To enable default per user profiles in Windows 9x / Me, launch the System Policy Editor, then select -> , then click on the Local Computer icon, click on Windows 98 System, select User Profiles, click on the enable box. Do not forget to save the registry changes.
To modify the registry directly, launch the Registry Editor (regedit.exe), select the hive HKEY_LOCAL_MACHINE\Network\Logon. Now add a DWORD type key with the name "User Profiles", to enable user profiles set the value to 1, to disable user profiles set it to 0.
When a user logs on to a Windows 9x / Me machine, the local profile path, HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\ProfileList, is checked for an existing entry for that user:
If the user has an entry in this registry location, Windows 9x / Me checks for a locally cached version of the user profile. Windows 9x / Me also checks the user's home directory (or other specified directory if the location has been modified) on the server for the User Profile. If a profile exists in both locations, the newer of the two is used. If the User Profile exists on the server, but does not exist on the local machine, the profile on the server is downloaded and used. If the User Profile only exists on the local machine, that copy is used.
If a User Profile is not found in either location, the Default User Profile from the Windows 9x / Me machine is used and is copied to a newly created folder for the logged on user. At log off, any changes that the user made are written to the user's local profile. If the user has a roaming profile, the changes are written to the user's profile on the server.
On MS Windows NT4 the default user profile is obtained from the location %SystemRoot%\Profiles which in a default installation will translate to C:\WinNT\Profiles. Under this directory on a clean install there will be three (3) directories: Administrator, All Users, Default User.
The All Users directory contains menu settings that are common across all system users. The Default User directory contains menu entries that are customisable per user depending on the profile settings chosen/created.
When a new user first logs onto an MS Windows NT4 machine a new profile is created from:
| All Users settings |
| Default User settings (contains the default NTUser.DAT file) |
When a user logs onto an MS Windows NT4 machine that is a member of a Microsoft security domain the following steps are followed in respect of profile handling:
The users' account information which is obtained during the logon process contains the location of the users' desktop profile. The profile path may be local to the machine or it may be located on a network share. If there exists a profile at the location of the path from the user account, then this profile is copied to the location %SystemRoot%\Profiles\%USERNAME%. This profile then inherits the settings in the All Users profile in the %SystemRoot%\Profiles location.
If the user account has a profile path, but at it's location a profile does not exist, then a new profile is created in the %SystemRoot%\Profiles\%USERNAME% directory from reading the Default User profile.
If the NETLOGON share on the authenticating server (logon server) contains a policy file (NTConfig.POL) then it's contents are applied to the NTUser.DAT which is applied to the HKEY_CURRENT_USER part of the registry.
When the user logs out, if the profile is set to be a roaming profile it will be written out to the location of the profile. The NTuser.DAT file is then re-created from the contents of the HKEY_CURRENT_USER contents. Thus, should there not exist in the NETLOGON share an NTConfig.POL at the next logon, the effect of the provious NTConfig.POL will still be held in the profile. The effect of this is known as tatooing.
MS Windows NT4 profiles may be Local or Roaming. A Local profile will stored in the %SystemRoot%\Profiles\%USERNAME% location. A roaming profile will also remain stored in the same way, unless the following registry key is created:
HKEY_LOCAL_MACHINE\SYSTEM\Software\Microsoft\Windows NT\CurrentVersion\winlogon\ "DeleteRoamingCache"=dword:00000001
Under MS Windows NT4 default locations for common resources (like My Documents may be redirected to a network share by modifying the following registry keys. These changes may be affected via use of the System Policy Editor (to do so may require that you create your owns template extension for the policy editor to allow this to be done through the GUI. Another way to do this is by way of first creating a default user profile, then while logged in as that user, run regedt32 to edit the key settings.
The Registry Hive key that affects the behaviour of folders that are part of the default user profile are controlled by entries on Windows NT4 is:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\
The above hive key contains a list of automatically managed folders. The default entries are:
Table 24.1. User Shell Folder registry keys default values
| Name | Default Value |
|---|---|
| AppData | %USERPROFILE%\Application Data |
| Desktop | %USERPROFILE%\Desktop |
| Favorites | %USERPROFILE%\Favorites |
| NetHood | %USERPROFILE%\NetHood |
| PrintHood | %USERPROFILE%\PrintHood |
| Programs | %USERPROFILE%\Start Menu\Programs |
| Recent | %USERPROFILE%\Recent |
| SendTo | %USERPROFILE%\SendTo |
| Start Menu | %USERPROFILE%\Start Menu |
| Startup | %USERPROFILE%\Start Menu\Programs\Startup |
The registry key that contains the location of the default profile settings is:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
Table 24.2. Defaults of profile settings registry keys
| Common Desktop | %SystemRoot%\Profiles\All Users\Desktop |
| Common Programs | %SystemRoot%\Profiles\All Users\Programs |
| Common Start Menu | %SystemRoot%\Profiles\All Users\Start Menu |
| Common Startup | %SystemRoot%\Profiles\All Users\Start Menu\Progams\Startup |
MS Windows XP Home Edition does use default per user profiles, but can not participate in domain security, can not log onto an NT/ADS style domain, and thus can obtain the profile only from itself. While there are benefits in doing this the beauty of those MS Windows clients that CAN participate in domain logon processes allows the administrator to create a global default profile and to enforce it through the use of Group Policy Objects (GPOs).
When a new user first logs onto MS Windows 200x/XP machine the default profile is obtained from C:\Documents and Settings\Default User. The administrator can modify (or change the contents of this location and MS Windows 200x/XP will gladly use it. This is far from the optimum arrangement since it will involve copying a new default profile to every MS Windows 200x/XP client workstation.
When MS Windows 200x/XP participate in a domain security context, and if the default user profile is not found, then the client will search for a default profile in the NETLOGON share of the authenticating server. ie: In MS Windows parlance: %LOGONSERVER%\NETLOGON\Default User and if one exits there it will copy this to the workstation to the C:\Documents and Settings\ under the Windows login name of the user.
This path translates, in Samba parlance, to the smb.conf [NETLOGON] share. The directory should be created at the root of this share and must be called Default Profile.
If a default profile does not exist in this location then MS Windows 200x/XP will use the local default profile.
On loging out, the users' desktop profile will be stored to the location specified in the registry settings that pertain to the user. If no specific policies have been created, or passed to the client during the login process (as Samba does automatically), then the user's profile will be written to the local machine only under the path C:\Documents and Settings\%USERNAME%.
Those wishing to modify the default behaviour can do so through three methods:
Modify the registry keys on the local machine manually and place the new default profile in the NETLOGON share root - NOT recommended as it is maintenance intensive.
Create an NT4 style NTConfig.POL file that specified this behaviour and locate this file in the root of the NETLOGON share along with the new default profile.
Create a GPO that enforces this through Active Directory, and place the new default profile in the NETLOGON share.
The Registry Hive key that affects the behaviour of folders that are part of the default user profile are controlled by entries on Windows 200x/XP is:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\
The above hive key contains a list of automatically managed folders. The default entries are:
Table 24.3. Defaults of default user profile paths registry keys
| Name | Default Value |
|---|---|
| AppData | %USERPROFILE%\Application Data |
| Cache | %USERPROFILE%\Local Settings\Temporary Internet Files |
| Cookies | %USERPROFILE%\Cookies |
| Desktop | %USERPROFILE%\Desktop |
| Favorites | %USERPROFILE%\Favorites |
| History | %USERPROFILE%\Local Settings\History |
| Local AppData | %USERPROFILE%\Local Settings\Application Data |

| Recent | %USERPROFILE%\Recent |
| SendTo | %USERPROFILE%\SendTo |
| Start Menu | %USERPROFILE%\Start Menu |
| Startup | %USERPROFILE%\Start Menu\Programs\Startup |
| Templates | %USERPROFILE%\Templates |
There is also an entry called "Default" that has no value set. The default entry is of type REG_SZ, all the others are of type REG_EXPAND_SZ.
It makes a huge difference to the speed of handling roaming user profiles if all the folders are stored on a dedicated location on a network server. This means that it will NOT be necessary to write the Outlook PST file over the network for every login and logout.
To set this to a network location you could use the following examples:
%LOGONSERVER%\%USERNAME%\Default Folders
This would store the folders in the user's home directory under a directory called Default Folders You could also use:
\\SambaServer\FolderShare\%USERNAME%
in which case the default folders will be stored in the server named SambaServer in the share called FolderShare under a directory that has the name of the MS Windows user as seen by the Linux/Unix file system.
Please note that once you have created a default profile share, you MUST migrate a user's profile (default or custom) to it.
MS Windows 200x/XP profiles may be Local or Roaming. A roaming profile will be cached locally unless the following registry key is created:
HKEY_LOCAL_MACHINE\SYSTEM\Software\Microsoft\Windows NT\CurrentVersion\winlogon\"DeleteRoamingCache"=dword:00000001
In which case, the local cache copy will be deleted on logout.
THe following are some typical errors/problems/questions that have been asked.
With samba-2.2.x the choice you have is to enable or disable roaming profiles support. It is a global only setting. The default is to have roaming profiles and the default path will locate them in the user's home directory.
If disabled globally then no-one will have roaming profile ability. If enabled and you want it to apply only to certain machines, then on those machines on which roaming profile support is NOT wanted it is then necessary to disable roaming profile handling in the registry of each such machine.
With samba-3.0.0 (soon to be released) you can have a global profile setting in smb.conf _AND_ you can over-ride this by per-user settings using the Domain User Manager (as with MS Windows NT4/ Win 2Kx).
In any case, you can configure only one profile per user. That profile can be either:
| A profile unique to that user |
| A mandatory profile (one the user can not change) |
| A group profile (really should be mandatory ie:unchangable) |
“ I dont want Roaming profile to be implemented, I just want to give users local profiles only. ... Please help me I am totally lost with this error from past two days I tried everything and googled around quite a bit but of no help. Please help me. ”
I know of no registry keys that will allow auto-deletion of LOCAL profiles on log out
| can use auto-delete on logout option |
| requires a registry key change on workstation |
- should be preserved on a central server - workstations 'cache' (store) a local copy - used in case the profile can not be downloaded at next logon
- loaded from a cetral place
- can be personal or group - can NOT be changed (except by an administrator
A WinNT4/2K/XP profile can vary in size from 130KB to off the scale. Outlook PST files are most often part of the profile and can be many GB in size. On average (in a well controlled environment) roaming profie size of 2MB is a good rule of thumb to use for planning purposes. In an undisciplined environment I have seen up to 2GB profiles. Users tend to complain when it take an hour to log onto a workstation but they harvest the fuits of folly (and ignorance).
The point of all the above is to show that roaming profiles and good controls of how they can be changed as well as good discipline make up for a problem free site.
Microsoft's answer to the PST problem is to store all email in an MS Exchange Server back-end. But this is another story ...!
| If lots of users user each machine - lot's of local disk storage needed for local profiles |
| Every workstation the user logs into has it's own profile - can be very different from machine to machine |
| The network administrator can control EVERY aspect of user profiles |
| With the use of mandatory profiles - a drastic reduction in network management overheads |
| User unhappiness about not being able to change their profiles soon fades as they get used to being able to work reliably |
I have managed and installed MANY NT/2K networks and have NEVER found one where users who move from machine to machine are happy with local profiles. In the long run local profiles bite them.
“ When the client tries to logon to the PDC it looks for a profile to download where do I put this default profile. ”
Firstly, your samba server need to be configured as a domain controller.
server = user
os level = 32 (or more)
domain logons = Yes
Plus you need to have a [netlogon] share that is world readable. It is a good idea to add a logon script to pre-set printer and drive connections. There is also a facility for automatically synchronizing the workstation time clock with that of the logon server (another good thing to do).
To invoke auto-deletion of roaming profile from the local workstation cache (disk storage) you need to use the Group Policy Editor to create a file called NTConfig.POL with the appropriate entries. This file needs to be located in the netlogon share root directory.
Oh, of course the windows clients need to be members of the domain. Workgroup machines do NOT do network logons - so they never see domain profiles.
Secondly, for roaming profiles you need: logon path = \\%N\profiles\%U (with some such path) logon drive = H: (Z: is the default) Plus you need a PROFILES share that is world writable.
