How can I determine which w3wp.exe process belongs to which web site?

Question

I have an IIS6 web server that is hosting two application pools. Occasionally, one of the w3wp processes will spike the CPU for a while, and both app pools seem to suffer the consequences. I'm not sure which one is which, and without that information I don't know which application to blame.

How can I tell which w3wp belongs to which App Pool?

Answer 1

c:\windows\system32\cscript iisapp.vbs

Answer 2

lisapp.vbs from microsoft is for exactly that.

Answer 3

You can also get this information from the IIS Debug Diagnostic Tool

Answer 4

You can also use Process Explorer from Sysinternals. Right click the columns at the top and select the "Command Line" column. In the Command Line column you will see the name of the web app included in the full command.
