Configuring IIS application pool settings using PowerShell

Question

I'm trying to set the value of Enable32BitApplication and LoadUserProfile of an IIS app pool to True using PowerShell by running the following Cmdlets:

(Get-IISAppPool -Name DefaultAppPool).enable32BitAppOnWin64 = $True
(Get-IISAppPool -Name DefaultAppPool).ProcessModel.LoadUserProfile = $True

When I retrieve these values using PowerShell, it looks like the Cmdlets have run successfully, but when I try to check it in the GUI, I can note that it did not work. That's why I tried to test the website of the application pool in action, and I figured out that these Cmdlets does not work. Can anyone help me with the right PowerShell Cmdlets?

Answer 1

In order for it to work by modifying the object returned by Get-IISAppPool you have to call Start-IISCommitDelay prior to changing the values and then Stop-IISCommitDelay after making the changes. So in your case it'd be:

Start-IISCommitDelay
(Get-IISAppPool -Name DefaultAppPool).enable32BitAppOnWin64 = $True
(Get-IISAppPool -Name DefaultAppPool).ProcessModel.LoadUserProfile = $True
Stop-IISCommitDelay
