I have a problem with IIS 6.0 on WInServer 2003. It was running 4 different sites(2x2 - Live and Test). Time to time one specific site not respond or working slow but other working correctly, in task manager cpu load by 60%. When IIS restarted - all working
correctly to next hang. In log files (IIS and System) any errors. Server - Xeon3Ghz+1Gb, free space 100Gb. memory used max 80%. If change application name it seems that working correctly, but I not sure that this is problem. Please advise what happend?

Are these ASP.NET sites?
When the specific site runs into problem, how much free physical memory does the system have?
Do you see anything in the event viewer when the problem happens?
Once you restart IIS, how long will it take before the same problem occurs again?

Please be advised to isolate ASP.net sites into different application pools. Then check in task manager or process explorer to verify which w3wp.exe instance(pid) is with high CPU utilization.
After that, run cscript iisapp.vbs under a command line, system32 folder to check the w3wp.exe belongs to which pool/site.
This should help you find out the problematic site with potential defect code.
