You can use the command-line script iisapp.vbs, which is stored in systemroot\system32, to view any worker processes that are currently running. This command is often used for troubleshooting.

The computer issuing the command must be running WindowsXP or a Windows.NET Server family system. The computer that the command affects must be running Windows.NET with IIS6.0.

important Important You must be a member of the Administrators group on the local computer to run scripts and executables, or you must have been delegated the appropriate authority. As a security best practice, log on to your computer using an account that is not in the Administrators group, and then use the Runas command to run your script or executable as an administrator. From the command prompt, type runas /user:administrative_accountname "script or executable command".
