One of my clients has an NT 4.0 server with DOS, Win95, Win98 and NT workstations. Everything is fine except:

DOS work station Fran (computer name and user name in system.ini) works fine until DOS work station Larry (computer name = Other and user name = Larry in system.ini) tries to log on.

We then get one of two errors:
A. Drive door is open
or
B. Network reading drive f:


We've checked the system.ini and autoexec.bat to see if there

issues, but cannot find them.

Does anyone have any suggestions?
