Microsoft Knowledge Base Article 178631 contains the following summary:
The Microsoft Distributed File System (Dfs) can be used to simulate
NetWare's MAP ROOT utility, allowing users to map a drive letter to a
directory that is not itself shared. This is especially useful for mapping
to users' home directories without creating individual shares.
Here is an example:
- Create a folder called Homedirs on the server.
- Create user folders beneath Homedirs.
- Install Microsoft Dfs and set Homedirs as the root for the Dfs. Consult the Readme.doc for detailed instructions for setting up the Dfs.
net use u: \\DFSServer\Homedirs\User1Drive U will be mapped to User1, even though Homedirs is the share point. This format is also acceptable when mapping drives from within Explorer.
