I have run into a problem recently which is driving me crazy. :) Our current setup is as follows: FreeBSD 2.2.8 server running Samba 2.0.5a The Samba server auths against an NT 4.0 Server (SP5). Certain NT machines in our network (NT 4.0 Server SP4), have problems accessing shares on the samba server. After a clean boot, they will be able to successfully access the shares for about 1/2 hour, at which time the server begins logging the following: password server PDC-VAN rejected the password If I try any other valid username/password for our network on one of these 'bad' clients, they fail as well. Rebooting the client appears to fix the problem for about a 1/2 hour, at which time they must reboot again. Any suggestions would be greatly appreciated :) Thanks..
