I have a pretty dumb one:
WinNT has a built in mechanism to lock users out as soon as the max
connection limit (NT Licenses) is reached.
Could it be that the NT-Server has not enough licenses entered in the
setup?

Well, this is really a last-chance idea, but something similar happened
to a friend of mine last year :-)
