NT Lockout

I’m running Windows NT 4.0 workstation. Using the Novell client 4.61 to log in to the Novell network. I’m able to log in to the Novell side but it then comes up and asks me for an NT password. No matter what user I enter with any password with any domain or even try to log in localy it gives me the error of incorrect password. I can’t even connect to it over the nework. Same error. Now, I believe it might of crashed but not for sure. Does anybody have any IDEAS!!
