->Under MS Windows platforms, particularly those following the release of MS Windows
-NT4 and MS Windows 95) it is possible to create a type of file that would be placed
-in the NETLOGON share of a domain controller. As the client logs onto the network
-this file is read and the contents initiate changes to the registry of the client
-machine. This file allows changes to be made to those parts of the registry that
-affect users, groups of users, or machines.</P
-><P
->For MS Windows 9x/Me this file must be called <TT
-CLASS="FILENAME"
->Config.POL</TT
-> and may
-be generated using a tool called <TT
-CLASS="FILENAME"
->poledit.exe</TT
->, better known as the
-Policy Editor. The policy editor was provided on the Windows 98 installation CD, but
-dissappeared again with the introduction of MS Windows Me (Millenium Edition). From
-comments from MS Windows network administrators it would appear that this tool became
-a part of the MS Windows Me Resource Kit.</P
-><P
->MS Windows NT4 Server products include the <SPAN
-CLASS="emphasis"
-><I
-CLASS="EMPHASIS"
->System Policy Editor</I
-></SPAN
->
-under the <TT
-CLASS="FILENAME"
->Start -&#62; Programs -&#62; Administrative Tools</TT
-> menu item.
-For MS Windows NT4 and later clients this file must be called <TT
-CLASS="FILENAME"
->NTConfig.POL</TT
->.</P
-><P
->New with the introduction of MS Windows 2000 was the Microsoft Management Console
-or MMC. This tool is the new wave in the ever changing landscape of Microsoft
-methods for management of network access and security. Every new Microsoft product
-or technology seems to obsolete the old rules and to introduce newer and more
-complex tools and methods. To Microsoft's credit though, the MMC does appear to
-be a step forward, but improved functionality comes at a great price.</P
-><P
->Before embarking on the configuration of network and system policies it is highly
-advisable to read the documentation available from Microsoft's web site regarding
-<A
-HREF="http://www.microsoft.com/ntserver/management/deployment/planguide/prof_policies.asp"
-TARGET="_top"
->Implementing Profiles and Policies in Windows NT 4.0 from http://www.microsoft.com/ntserver/management/deployment/planguide/prof_policies.asp</A
-> available from Microsoft.
-There are a large number of documents in addition to this old one that should also
-be read and understood. Try searching on the Microsoft web site for "Group Policies".</P
-><P
->What follows is a very brief discussion with some helpful notes. The information provided
-here is incomplete - you are warned.</P

-><P
->You need the Win98 Group Policy Editor to set Group Profiles up under Windows 9x/Me.
-It can be found on the Original full product Win98 installation CD under
-<TT
-CLASS="FILENAME"
->tools/reskit/netadmin/poledit</TT
->. Install this using the
-Add/Remove Programs facility and then click on the 'Have Disk' tab.</P
-><P
->Use the Group Policy Editor to create a policy file that specifies the location of
-user profiles and/or the <TT
-CLASS="FILENAME"
->My Documents</TT
-> etc. stuff. Then
-save these settings in a file called <TT
-CLASS="FILENAME"
->Config.POL</TT
-> that needs to
-be placed in the root of the [NETLOGON] share. If Win98 is configured to log onto
-the Samba Domain, it will automatically read this file and update the Win9x/Me registry
-of the machine as it logs on.</P
-><P
->Further details are covered in the Win98 Resource Kit documentation.</P
-><P
->If you do not take the right steps, then every so often Win9x/Me will check the
-integrity of the registry and will restore it's settings from the back-up
-copy of the registry it stores on each Win9x/Me machine. Hence, you will
-occasionally notice things changing back to the original settings.</P
-><P
->Install the group policy handler for Win9x to pick up group policies. Look on the
-Win98 CD in <TT
-CLASS="FILENAME"
->\tools\reskit\netadmin\poledit</TT
->.
-Install group policies on a Win9x client by double-clicking
-<TT
-CLASS="FILENAME"
->grouppol.inf</TT
->. Log off and on again a couple of times and see
-if Win98 picks up group policies. Unfortunately this needs to be done on every
-Win9x/Me machine that uses group policies.</P

-Further, although the Windows 95 Policy Editor can be installed on an NT4

-the NT Server will run happily enough on an NT4 Workstation.</P
-><P
->You need <TT

-It is convenient to put the two *.adm files in the <TT

->c:\winnt\inf</TT
->
-directory which is where the binary will look for them unless told otherwise. Note also that that
-directory is normally 'hidden'.</P
-><P
->The Windows NT policy editor is also included with the Service Pack 3 (and
-later) for Windows NT 4.0. Extract the files using <B
-CLASS="COMMAND"
->servicepackname /x</B
->,
-i.e. that's <B
-CLASS="COMMAND"
->Nt4sp6ai.exe /x</B
-> for service pack 6a. The policy editor,
-<B
-CLASS="COMMAND"
->poledit.exe</B
-> and the associated template files (*.adm) should
-be extracted as well. It is also possible to downloaded the policy template
-files for Office97 and get a copy of the policy editor. Another possible
-location is with the Zero Administration Kit available for download from Microsoft.</P

- NTConfig.POL file were applied to the client machine registry and that apply to the

->Windows NT4 System policies allows setting of registry parameters specific to
-users, groups and computers (client workstations) that are members of the NT4
-style domain. Such policy file will work with MS Windows 2000 / XP clients also.</P
-><P
->New to MS Windows 2000 Microsoft introduced a new style of group policy that confers
-a superset of capabilities compared with NT4 style policies. Obviously, the tool used
-to create them is different, and the mechanism for implementing them is much changed.</P
-><P
->The older NT4 style registry based policies are known as <SPAN
-CLASS="emphasis"

-CLASS="EMPHASIS"

->
-in MS Windows 2000/XP Group Policy Objects (GPOs). The later includes ability to set various security

-users' desktop (including: the location of <SPAN
-CLASS="emphasis"
-><I
-CLASS="EMPHASIS"
->My Documents</I
-></SPAN
-> files (directory), as
-well as intrinsics of where menu items will appear in the Start menu). An additional new
-feature is the ability to make available particular software Windows applications to particular
-users and/or groups.</P
-><P
->Remember: NT4 policy files are named <TT
-CLASS="FILENAME"
->NTConfig.POL</TT
-> and are stored in the root
-of the NETLOGON share on the domain controllers. A Windows NT4 user enters a username, a password
-and selects the domain name to which the logon will attempt to take place. During the logon
-process the client machine reads the NTConfig.POL file from the NETLOGON share on the authenticating
-server, modifies the local registry values according to the settings in this file.</P
-><P
->Windows 2K GPOs are very feature rich. They are NOT stored in the NETLOGON share, rather part of
-a Windows 200x policy file is stored in the Active Directory itself and the other part is stored
-in a shared (and replicated) volume called the SYSVOL folder. This folder is present on all Active
-Directory domain controllers. The part that is stored in the Active Directory itself is called the
-group policy container (GPC), and the part that is stored in the replicated share called SYSVOL is
-known as the group policy template (GPT).</P
-><P
->With NT4 clients the policy file is read and executed upon only aas each user log onto the network.
-MS Windows 200x policies are much more complex - GPOs are processed and applied at client machine
-startup (machine specific part) and when the user logs onto the network the user specific part
-is applied. In MS Windows 200x style policy management each machine and/or user may be subject
-to any number of concurently applicable (and applied) policy sets (GPOs). Active Directory allows
-the administrator to also set filters over the policy settings. No such equivalent capability
-exists with NT4 style policy files.</P
