Listing Running Web Applications Using Iisapp.vbs

Updated: August 22, 2005

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1

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\Administrator cmd to open a command window with administrator rights and then type cscript.exe ScriptName (include the script's full path and any parameters).

This topic includes the following information:

  • Syntax: The order in which you must type a command and any arguments and options that follow it.

  • Parameters: The values that are given to variables in the command.

  • Examples: Sample code and an explanation of the results.


iisapp [ /a AppPoolName | /p PID]


/a AppPoolName

Optional. Specifies the name of a particular application pool.

/p PID

Optional. Specifies an application pool by its ID number.


Example 1:

The following command displays all of the application pools that are running on the local computer:


In response, iisapp displays all of the currently running applications, identifying each application pool by its process ID (PID) and application pool ID (AppPoolID). Iisapp omits all of the optional parameters and accepts the default values.

W3wp.exe PID: 2232 AppPoolID: DefaultAppPool

W3wp.exe PID: 2608 AppPoolID: MyAppPool

Example 2:

Use the following command to view a specific application by entering its PID:

iisapp /p 2608

In response, iisapp displays the specified application.

W3wp.exe PID: 2608 AppPoolID: MyAppPool
