Hi

I see in Task Manager on my Win 2003 server the w3wp overshoots to 99% thus taking full CPU power .. this happens many many time during the day .. causing the Alert of IPAlerts to trigger, thus emailing me...

My Question:
How do i know What is causing it ... which site is causing this overshoot!

Have many sites ... so need to know which one of these sites or if any thing else is causing it!

Please advice

Thanks

Most likely due to bad code or badly written dlls somewhere. You could try iisstate to debug the w3wp.exe proecess:

Then post the debug logs in this newsgroup:
microsoft.public.inetserver.iis

and they will help you out.
