Hi,
What you're actually seeing is that the login process isn't completing. If
you use ctrl-F1 (ICA session) or ctrl-alt-delete (console) and start a new
task (explorer) you'll probably get a desktop.
Causes can vary, but I'd check out the IMA service and the local host cache.
If the login process accesses network resources that aren't available, you
could also see this sort of problem.
Actaually had an instance today where a server appeared to freeze, problem
was due to a user account having expired, causing authentication errors
against a backend file server and essentially blocking all i/o to that
server. Checked the eventlog (security) on the file server and it was full
of authentication errors. Logged that user off, and the server recovered.
regards,
Rick

Subject: [THIN] Citrix locking up...
(1 Citrix Server, Windows 2000 SP2,Metaframe XPs FR2)
This morning the Citrix server is regularly locking up. Users that are =
currently in Citrix the applications running freeze, but they can start =
new applications from the start menu which then freeze themselvies after =
a few minutes. =20
Anyone trying to log in, either via the Console, RDP, or ICA, it allows =
the userid and password to be entered but then hangs with just the =
desktop background showing. The only thing that I can do then is reboot =
the server.
Once the server is in this state, I have managed to launch Task Manager, =
and the CPU usage is around 90% to 95% idle and memory usage is low.
The only thing that appears in the event log prior the server getting in =
this state is the informational application log message:
Source: Winlogon
Event ID: 1002
Description: The shell stopped unexpectedly and Explorer.exe was =
restarted.
The server has now done this 4 times in the last 2 hours.
Any ideas as to why this is happening, or any pointers to=20
I would be very grateful for any help on this!
Thanks,
