Hi there..
I use the freeware (and superb) KIX32 in our NT/2K environment.
It's script based, but an absolute doddle to use. You just have the KIX32 program on each workstation, and a script which has something along the lines of
addprinterconnection("\\servername\printername"
to reconnect to the printers and
use J: "\\servername\sharename"
to get (say) drive J: mapped to a particular share.
KIX32 is brilliant, and will make your life SO much easier. Honest.. You can have the script do certain operations based on the user's name, group membership, or even the workstation's name.
Once you have the script, you would have a shortcut in the All Users startup with something like
C:\WINNT\KIX32\KIX32.exe C:\winnt\kix32\scripts\myscript.kix
You could (of course) have the program and scripts living on a server, but this might not be such a good idea if you have a very large user base all trying to log in more or less at the same time.
kixtart.org and kixscripts.com should get you started.
Cheers,
Gerard
