 When enumerating what could be a server name or a workgroup name, first
 check for an existing server structure.  If none exists, then go through
 the previous determination of whether it's a serrver or a workgroup.  This
 should avoid doing a NetBIOS name query each time, if we've already
 connected to the specified server.  (While we're at it, clean up indenting
 and line length in this area of code.)
