Powershell script to change application pool credentials

  • Article

 

With this powershell script you will be able to change the user name and password of any application pool in which the user equals to a specific one. This is meaning that it will replace the existing credentials with new ones (in all the application pools)

 

Pre-Requisites:

  1. The ps1 file should be executed elevated. If not the change method will fail.


Functionalities

  • You can change the user name and password of any application pool that has a specific user.
  • It can run only in the running server.


Parameters

All parameters are mandatory. If you don’t provide them, powershell will ask.

  • OLDUser: This would be the old user name. The script will filter all the application pools matching this User and will replace it with the NewUser parameter
  • NewUser: this is the user name that the application pool will use.
  • NewPassword: password of the NewUser
  • AppCmdToolLocation: Location of the appcmd command. By default is located in c:\windows\system32\inetsrv\appcmd.exe.

Example:

.\changeUserAppPool.ps1 –OldName .\OLDAdmin –NewUser .\NewAdmin –NewPassword NewPassword –appCmdToolLocation c:\windows\system32\inetsrv\appcmd.exe
