IIS Application pool PID

is anyone familiar with a way to get the Application pool that is associated with a process ID ? I am using Win32_Process to query the W3WP services and return the PID now I am trying to get the app pool associated with it.

From stackoverflow

• ServerManager serverManager = new ServerManager();
  ApplicationPoolCollection applicationPoolCollection = serverManager.ApplicationPools;
  

  Try working with this and it should get you what you need.

• If you are just using command line to figure it out ad-hoc you can do this too:

  The script is already placed in systemroot\system32 on Windows Server 2003 so simply go to your Command Prompt and type in iisapp.vbs (the .vbs is optional) and you'll have an instant list of all the App Pool information you've always wanted to know. You may need to type cscript iisapp.vbs if CScript isn't your default WSH script host.

  Let's see an example of the output:

  W3WP.exe PID: 1468 AppPoolId: AppPoolForSite1.com
  W3WP.exe PID: 3056 AppPoolId: AppPoolForSite2.com
  W3WP.exe PID: 1316 AppPoolId: AppPoolForSite3.com
  

  Direct from the horse's mouth, Microsoft documents this:

  Adonis L : Thanks I can review this script for code example

• On Windows Server 2008 this has changed.

  in systemroot\system32\inetsrv you find the appcmd.exe

  using

  appcmd list wp

  you get a list of all the worker processes and which apppool they are serving.

  Doug : This doesn't seem to list app pools that run as a machine user (SYSTEM/NETWORK SERVICE)... any thoughts?

• If you're running on Windows Server 2008 and you ONLY want the PID, to feed to another script or command, you can use this:

  c:\windows\system32\inetsrv\appcmd list wps /apppool.name:"My Application Pool" /text:WP.NAME
  

  For example, to create a batch script that creates a memory dump of a particular app pool, use this:

  c:\windows\system32\inetsrv\appcmd list wps /apppool.name:"My Application Pool" /text:WP.NAME > "%temp%\pid.txt"
  for /F %%a in (%temp%\pid.txt) do c:\debugger\adplus.exe -hang -o d:\dumps -p %%a
