As has been mentioned frequently in this post, you cannot do deep mapping in NT4

You can only map a drive to the root of the share level.

You have two options. Either share out every home directory and map to it, or use SUBST.

If you want to your SUBST to simulate deep mapping then do the followuing:
Code:
use Y: "\\server\users$$"
Shell '"%COMSPEC%" /C SUBST H: Y:\'+@USERID


The Y: drive is mapped to the root of the share, as that is all NT will allow. You will see the Y: drive mapping in "net use".

The H: drive will not appear in "net use". It will appear in explorer though, and it will be mapped to the users' home directory.

Oddly, when I tested this the drive appears labled as "disconnected network drive" in Explorer on WinXP.
