Network was working fine when I left. When I in this a.m. - no one, including myself could log in to their systems. The system has told them that their logon password is in correct for the DOMAIN. I can log in as the Adminiistrator with its passwordbut not as myself. I've restarted all systems and still NoGo. I can see all Domains and can connect from the server. But I cannot connect from a workstation in the one Domain.

First thing to check is the network:
Is the cabling ok?
Can you ping the other machine?

Last time that happened I found a bad patch cable to the server.

Cat 5 cabling has Tranmit and Recieve cycles I have seen one side break down and cause the same symptoms you are describing.

1. Identify if your cabling is working.
2. Check the space you have on the NT sever validating your logons. More specifically on your C partitions, minimum space should be 100 MB of free space.
3. Check your network infrastructure, your network might be saturated with more users than your server can cope with. Good Luck

First thing to check is Services and amke sure Net Login is started and server is started. Next look at Event Viewer and look for any unusual entries.
If no-one can get into server then a reboot should do no harm, then try and log in again.
Best of Luck
