I am running

Win2000 SP4
Citrix meteframe xp release 3
novell Client 4.91 sp 2

When user login to the windows 2000 server the Novell login goes thru
then when the user logs on to the windows login an error message box
with " Windows nt security message" "unexpected login error 3221225659"
appears and dosen't allow access to the server.

Once rebooted users are able to login. This has happened several times

I know the username and passwords are correct

any help would be appreciated
