MetaFrame or Citrix 1.8

I have citrix metaframe 1.8 server installed on w2000 server. Just recently
I installed SP4 and applied the hotfix in article q822428. I think this
problem started after SP4.

Once in a while, a citrix user logging in to the server will hang at the
logging in process. On the w2000 server task manager, LSASS.exe and
WINLOGON.exe are using up the CPU usage from 30 to 50%. The server will slow
down and everyone connected to it. The only way to stop this is to
disconnect the user from the citrix console. The CPU usage for LSASS.exe and
WINLOGON.exe will drop to 0%.

This might be a citrix problem but is there a know issue with LSASS and
WINLOGON? or SP4? How can I prevent this from happening?
