Hey guys I was wondering if anyone could help me with this script. 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.

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[$]}

or these

$server = 'localhost'

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

query session /server:$server
qwinsta /server:$server

query user /server:$server
quser /server:$server

qprocess explorer.exe /server:$server
