Matt, Check out the disk I/O. We had a problem once that caused all sessions to freeze when other users where logging in and out. We used perfmon to track it down to a disk I/O problem. After applying new drivers for the RAID controller, the problem disappeared. This was a Compaq/HP, so we just applied the latest SoftPack. Hope that helps. Cheers, Jeremy. _____ From: Matt Barys [mailto:MBarys@xxxxxxxxxxxxxxx] Sent: Friday, 16 July 2004 4:55 AM To: 'thin@xxxxxxxxxxxxx' Subject: [THIN] Citrix sessions freezing Hi everyone, This is a continuation from my question yesterday. I talked about user sessions freezing for a few seconds to up to a minute when in Office apps. Well, now it's happening in anything desktop related. Any clues what could be causing this? The only thing that has changed in the last few weeks is that I upgraded my Metaframe 1.8 servers to SP4 of Metaframe. Any guidance would be much appreciated. These boxes are all on Windows 2000 SP4.
