Listing Running Web Applications Using Iisapp.vbs (IIS 6.0)

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 Windows XP or a member of the Windows Server 2003 family. The computer that the command affects must be running a member of the Windows Server 2003 family with IIS 6.0.


You must be a member of the Administrators group on the local computer to run scripts and executables. As a security best practice, log on to your computer by 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. At a command prompt, type runas /profile /User:MyComputer\Administratorcmd to open a command window with administrator rights and then type cscript.exeScriptName (include the script's full path and any parameters).

This topic includes the following information:
