What I am trying to do its log off all users in our conference rooms after a given idle time. What I am trying to do is find all session id's and log off all active sessions. I am not worried about losing work as these are conference room computers. The problem I have is that I can get the session id for the current logged in user but not for all the users logged in. If anyone has any insight it would be greatly appreciated.

Answer 1

here are some options that may be of use

powershell way

$computer = 'localhost'
$owners = @{}
Get-WmiObject win32_process -ComputerName $computer -Filter 'name = "explorer.exe"' | % {$owners[$_.handle] = $_.getowner().user}
Get-Process -ComputerName $computer explorer | % {$owners[$_.id.tostring()]}

or these

$server = 'localhost'

(quser /server:$server) -replace '\s{2,}', ',' | ConvertFrom-Csv

# IDENTICAL
query session /server:$server
qwinsta /server:$server

# IDENTICAL
query user /server:$server
quser /server:$server

qprocess explorer.exe /server:$server

Answer 2

you can better do it with remote desktop session host configuration idle time limit to your desired time.
