Connect home directory to root of the share
User Configuration\Administrative Templates\System\Logon/Logoff
Restores the definitions of the %HOMESHARE% and %HOMEPATH% environment variables to those used in Windows NT 4.0 and earlier.
If you enable this policy, the system uses the Windows NT 4.0 definitions. If you disable this policy or do not configure it, the system uses the new definitions designed for Windows 2000.
Along with %HOMEDRIVE%, these variables specify the home directory of a user profile. The home directory is a persistent mapping of a drive letter on the local computer to a local or remote directory.
By default, in Windows 2000, %HOMESHARE% stores the fully qualified path to the home directory (such as \\server\share\dir1\dir2\homedir). Users can access the home directory and any of its subdirectories from the home drive letter, but they cannot see or access its parent directories. %HOMEPATH% stores a final backslash and is included for compatibility with earlier systems.
On Windows NT 4.0 and earlier, %HOMESHARE% stores only the network share (such as \\server\share). %HOMEPATH% stores the remainder of the fully qualified path to the home directory (such as \dir1\dir2\homedir). As a result, users can access any directory on the home share by using the home directory drive letter.
To specify a home directory in Windows 2000, in Active Directory Users and Computers or Local Users and Groups, right-click the name of a user account, click Properties, click the Profile tab, and in the Home folder section, click the Connect option and select a drive letter and home directory.
