Thanks for the information!

Although I have issued the command, Net Config Server
/autodisconnect:-1, it seemed to have fixed only 1 of the 4
DOS computers hanging up. It seems I have to looked at the
registry.

Btw, what is the minimum requirement for DOS computers in a
Windows NT environment?

P.S. Fred, Thanks for the response! :)
