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 Ulrich Mack rmack@xxxxxxxxxxxxxx <mailto:rmack@xxxxxxxxxxxxxx> Volante Systems 18 Heussler Terrace Milton 4064, Queensland Australia tel +61 7 32467777 -----Original Message----- From: Steve Rance [mailto:Steve.Rance@xxxxxxxxxxxxxxxxxxxxx] Sent: Wednesday, February 05, 2003 20:33 To: Thin @ Freelists (E-mail) Subject: [THIN] Citrix locking up...
