Might just be coincedence, but are you running APC Powerchute Business Edition 6.x? We had a range of problems with our Citrix servers on July 28th, which we traced back to this http://emea-en.apc.com/cgi-bin/emea_en.cfg/php/enduser/olh_adp.php?ISOCountr yCode=gb <http://emea-en.apc.com/cgi-bin/emea_en.cfg/php/enduser/olh_adp.php?ISOCount ryCode=gb&p_faqid=7202&p_olh=1> &p_faqid=7202&p_olh=1 The solution is to upgrade Powerchute to version 7.x. -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx]On Behalf Of Robert K Coffman Jr - Info From Data Corporation Sent: 03 August 2005 16:04 To: thin@xxxxxxxxxxxxx Subject: [THIN] Odd Server Strangeness Windows 2000/MF 1.8/Dual Processor Dell 2600/3GB. About a week ago, users began complaining that the server was slowing down or their session would freeze. On July 28th the server was rebooted, and after it came back up we noticed that logging into the console took a long time right after the reboot. Also, TS or ICA connections were not immediately accepted - it took about 15 minutes after the server rebooted before those connections could be made - however drive mappings, etc. were fine. When users log off, the logoff takes an extraordinary amount of time - 2-3 minutes. No roaming profiles. I am seeing event 1000 logged for that, along with the following text: Windows cannot unload your registry class file. If you have a roaming profile, your settings are not replicated. Contact your administrator. DETAIL Access is denied. , Build number ((2195)). Apparently MS has a hotfix for this. Additionally, at the same time (July 28) Veritas stopped backing up. Checking that, it seems that it no longer recognized the tape drive, although hardware manager shows the tape drive as working. Also, I noticed that any attempt to stop a service fails - eventually error 1053 - the service did not respond in a timely fashion is returned. PSKILL will stop the process but Services still shows status as "stopping" so I can't restart any I kill this way. I tried re-installing SP4, but it hung at "inspecting" until I ran it in safe mode - which worked but had no effect on any of the problems. Windows update returns an error - some hex, which led me to a KB article that referenced some software we don't run. Sorry I don't have any further info on that, server is currently rebooting. AV software is Symantec AV Version 8.0 I think. It says system is clean. Adaware removed 3 things (max TAC was 7) and Spybot S&D said system was clean. I'm about to open a per-incident support call with Microsoft - a step I've never taken, but something is seriously wrong with this server and I can't seem to get a handle on what. Any suggestions appreciated. - Bob Coffman
