Okay, I have a proof of concept script that looks like this for connecting to iTunes:
$username = Read-Host "Please enter your userid for the local machine"
$password = Read-Host "Please enter a password to be encrypted" -AsSecureString
$cred = New-Object System.Management.Automation.PSCredential -ArgumentList @($username,$password)
Invoke-Command -ScriptBlock {
$iTunes = New-Object -ComObject iTunes.application
$itunes | gm
} -ComputerName localhost -Credential $cred
However it is returning the following error:
Retrieving the COM class factory for component with CLSID {DC0C2640-1415-4644-875C-6F4D769839BA} failed due to the following error: 80080005.
+ CategoryInfo : ResourceUnavailable: (:) [New-Object], COMException
+ FullyQualifiedErrorId : NoCOMClassIdentified,Microsoft.PowerShell.Commands.NewObjectCommand
Where it gets interesting, is if I remove -ComputerName localhost -Credential $cred from the script block, it works fine:

Does anyone know why the credentials on the script block could be causing this problem?
The reason is I'm working on a way to run some iTunes tasks, when called from a LOCAL SYSTEM service, so in a way, I'm trying to elevate the call back to the logged-in user.
