Recycle IIS Application Pool Using PowerShell: "Calling a Call for Exception"

Question

It seems that a recent Windows update violated some of the features that I used to recycle IIS6 application pools, as it worked for several months now.

Exception calling "Recycle" : "Win32: The object identifier does not representException calling "Recycle" : "Win32: The object identifier does not represent a valid object.

The function that I used to recycle application pools was:

function recycle-pool($strServerName)
{
    $objWMI = [WmiSearcher] "Select * From IIsApplicationPool"
    $objWMI.Scope.Path = "\\" + $strServerName + "\root\microsoftiisv2"
    $objWMI.Scope.Options.Authentication = 6
    $pools = $objWMI.Get()
    foreach ($pool in $pools)
    {
        $pool.recycle()
        if (!$?)
        {
            Write-Host $pool.name " - ERROR"
        }
        else
        {
            Write-Host $pool.name " - Recycled"
        }
}

Any idea what the problem is and how should I approach this?

Answer 1

One of the application pools was stopped, which caused an error. Other application pools were disposed of fine. The above code is suitable for everyone else.

You can try to recycle with ADSI:

$server = "IIsServerName"  
$iis = [adsi]"IIS://$server/W3SVC/AppPools"  
$iis.psbase.children | foreach {  
    $pool = [adsi]($_.psbase.path)   
    $pool.psbase.invoke("recycle")  
}
