PowerShell Remote Logoff
I need help troubleshooting a problem with a PowerShell script that queries remote logged on users and then logs a selected user(s) off.
Here's the script -
The script keeps giving me the error "Log off failed! Please check manually"
I am running the script as admin. Not sure why it's doing this.
Here's the script -

$intAnswer = $a.popup($popup, `

Hi,
I see your using Invoke-RDUserLogoff cmdlet
Have you considered using/testing remote-pssessions?
Here's an example you can reference
$clientDCSession = new-PSSession -ComputerName $computer -Credential $DomainAdmincredAD
Invoke-Command -Session $clientDCSession -ScriptBlock ${function:Logoff-Session}
M

I adjusted the script a bit
Error - °Attempt log off:Invoke-RDUserLogoff : Cannot process argument transformation on parameter 'UnifiedSessionID'. Cannot convert value "console" to type "System.Int32". Error: "Input string was not in a correct format."
I suspect the root cause is tied to value conversion, but I don't know how to resolve it.

Invoke-RDUserLogoff is meant to act on the UnifiedSessionId from Get-RDUserSession. I don't think the parsing of the quser command output is always accurate. In that error it's showing that the session name is being passed instead of the session id. If you can I would try to utilize the Get-RDUserSession, so you don't have to parse the text output from quser.
