I run a Windows 2000 Server machine, and just this week it all of a sudden has been running EXTREMELY sluggishly while making regular computer tasks rather impossible to complete!!
I immediately checked its Task Manager to verify Performance and Processes, and sure enough the computer is sitting at CPU Usage: 100%. I have taken screen prints of the Performance and Processes screens and posted them at the following URLs for reference. In the Processes screen I presorted the list with the 'Mem Usage' column descending to determine what process is hogging the most memory:
The only thing I know that has changed in the system in the past few days is installing the latest hotfixes/service patches/packs from Microsoft for the month of July '04 for Windows 2000, Internet Explorer, and Outlook Express. Perhaps one or more of these might be a cause of the problem?
If anyone can help me to figure out what is happening I would be most grateful!
