How to change IIS app pool password on multiple servers at once remotely?

Question

We have a requirement to change our application's IIS app pool password everytime it expires. Currently, we have to manually login to each server and run a snippet of PowerShell code which changes the password.

Here is the code we run on each server on PS:

Import-Module WebAdministration
 $applicationPools = Get-ChildItem IIS:AppPools | where { $_.processModel.userName -eq "Domain\XXXXX12345" }
  
 foreach($pool in $applicationPools)
 {
     $pool.processModel.userName = "Doma\XXXXX12345"
     $pool.processModel.password = "XXXXXXXXXXXXXXXXX"
     $pool | Set-Item
 }
  
 Write-Host "Application pool passwords updated..." -ForegroundColor Magenta 
 Write-Host "" 
 Read-Host -Prompt "Press Enter to exit"

But is there a way we can do the same for a list of servers/VMs at once instead of having to login to each server, open PowerShell or IIS and manually change it on each server?

Any help would be greatly appreciated!

Answer 1

You could try to create an Azure DSC Configuration for this. This way you could provide a new configuration state every time the password expires.

Answer 2

could you try this below script:

$computerName = 'MyServerName' $appPoolName = 'DefaultAppPool'

Invoke-Command -ComputerName $computerName -args $appPoolName -ScriptBlock { param($appPoolName) $appPoolName.Stop()

$appPoolName | Set-ItemProperty -Name "processModel.username" -Value "Doma\XXXXX12345" $appPoolName | Set-ItemProperty -Name "processModel.password" -Value "XXXXXXXXXXXXXXXXX"

$targetpool.Start()

}

Write-Host "Application pool passwords updated..."
