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

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?

There are two ways in which I prefer "task manager" version.

By task manager,

Add "command line" column as shown in the images.

enter image description here enter image description here

By PowerShell,

cd C:\Windows\System32\inetsrv\
.\appcmd list wp

enter image description here

Goto cmd window then type c:\windows\system32\cscript c:\windows\system32\iisapp.vbs.

Now you will get the list of worker processes along with the app pool name.

For IIS7 you need to use APPCMD from %systemroot%\system32\inetsrv\ as an administrator

i.e.

%systemroot%\system32\inetsrv\appcmd list wp

See http://learn.iis.net/page.aspx/114/getting-started-with-appcmdexe/#HowToUse for more details

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.
