3.5 ways to display IIS App pool identities (usernames and passwords)

.NETway

[System.Reflection.Assembly]::LoadFrom( “C:\windows\system32\inetsrv\Microsoft.Web.Administration.dll” )
$mgr = New-Object Microsoft.Web.Administration.ServerManager
$mgr.ApplicationPools | % { $pm = $_.ChildElements[“processModel”]; Write-Host $_.Name $pm.Attributes[“userName”].Value$pm.Attributes[“password”].Value }

# Or, if you do not appreciate the brevity:

[System.Reflection.Assembly]::LoadFrom( “C:\windows\system32\inetsrv\Microsoft.Web.Administration.dll” )
$mgr = New-Object Microsoft.Web.Administration.ServerManager
$pools = $mgr.ApplicationPools
foreach ($pool in $pools)
{
        $processModel = $pool.ChildElements[“processModel”];
        Write-Host $pool.Name $processModel.Attributes[“userName”].Value $processModel.Attributes[“password”].Value
}

ADSI way

$pools = ([ADSI]“IIS://localhost/W3SVC/AppPools”).Children  
foreach ($pool in $pools)
{
        Write-Host $pool.Name, $pool.Properties.WAMUserName, $pool.Properties.WAMUserPAss
}

WMI way

Get-WMIObject -namespace root/MicrosoftIISv2 -Class IIsApplicationPoolSetting -Property Name, WAMUserName, WAMUserPass  | select Name,WAMUserName, WAMUserPass
