Hi
I've had an ongoing problem with my Win2000 web server for a while now. It's running IIS5 and SQL Server (which I initially thought was the problem but am almost sure now that the problem is in the Windows configuration).
Anyway my problem is that after being online for a couple of days, the server starts to run really slowly, regardless of traffic at the time, memory configuration of memory left (we've just added 512Mb so we know memory is not the problem). When I look at the CPU usage (using the Task Manager's processes tab and ordering the list by CPU usage) I notice that lsass.exe is using an inordinate amount of CPU time and when the CPU is being used heavily (i.e. when a database search is being carried out) it is the top user of the CPU - effectively hogging the computer's resources so everything else runs slowly. Lsass.exe also uses a lot of CPU time when the system has first been rebooted and runs well and then seems to just use more and more. My own computer doesn't do this - obviously lsass.exe is running but it comes way down the list and almost never moves into pole position (that is, it is never the one process that uses the most CPU time).
What does lsass.exe do? What settings might cause it to use so much CPU time? Can I disable it or at least set it to a lower appetite, as it were? Please help.
