Windows NT does not currently support the ability to map a drive letter on a client to a directory on a server, unless the directory is shared. This function, known in other network implementations as MAP ROOT, is desirable for connecting users directly to their home directories on the server.

An alternative for this is to individually share each user's home directory. This can be a labor-intensive process, especially for existing installations with large numbers of users. However, this process can be automated.

This workaround will work on all Windows clients, including the Microsoft Client Version 3.0 for MS-DOS, Windows for Workgroups, Windows 95 and Windows NT Workstation versions 3.51 and 4.0.

The following command, which can be used in a batch file, will automatically share out each user's home directory with permissions for that user only, if the directory currently exists and has the same name as the user. The ability to create a share requires Administrative Rights.
FOR %%X IN (list of users) DO RMTSHARE \\SERVER\%%X=C:\USERS\%%X /GRANT %%X:F
NOTE: Because RMTSHARE is a resource kit utility, this batch file requires the Windows NT Server Resource Kit to be installed on the computer on which it is run.

Each share will be created with the user's name and the Full Control permission will be granted to the user for that share. Memory resources are used for each share on a server. Therefore, it is advisable to load- balance by dividing the home directories evenly among several servers.

More information

  1. Use the following procedure to obtain a list of all user home directories:
    1. Open an MS-DOS command prompt on the computer where the user home directories reside.
    2. Change to the root user directory (that is, C:\Users)
    3. Get a directory listing and pipe it to a text file using the following command:
      DIR *. /W >> C:\Temp\Userdirs.txt
    4. Use a word processor to remove extraneous text (date, and so forth) and separate each name by only one space.

      NOTE: The maximum number of characters on a command line is 255. Therefore, you will not be able to put more than 20 to 30 user names on each line. Repeat the command several times for each block of users.
  2. Modify each line to look like the example line above. The finished file will look something like this:

    NOTE: Each two-line pair should be on one line.



  3. Save the file as a batch file and carry it out from the MS-DOS command prompt.
