I have a domain enviornment with a Win2K server and Win 2K\98\95 workstations. Randomly users are being locked out of the network (as if they tried to log in incorrectly). I can unlock their account and they are fine until the next time. I have run Windows update on the WS, installed SP2 on the server, deleted the .PWL files on the WS’s, deleted and re-created the exchange profiles, installed the DSclient package on all WS. The event log does show invalid attempts to log in, but this can happen while a user is at lunch and not even touching their machine. The server is running DHCP and WINS and there seems to be no problems with them. Any ideas
