There is a hotfix for this. I got it yesterday. Seemed to work KB904711 _____ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Kaftan, John Sent: Wednesday, November 02, 2005 10:07 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Win2K SP4 Rollup Does anybody have experience with this? What is a rollup opposed to a typical SP4 install? A buddy of mine ran this one of his Citrix servers and spent the day trying to recover. His Proc was pegged at 90% and nobody could log in. He couldn't see what was causing it. Eventually he uninstalled the rollup and all was well.
