How to kill all RDP sessions using powershell script - windows

Question

I am writing powershell script like below but unable to read a sessionids from the query result then kill all the active sessions.
$queryResults = quser /server:$server; Write-Output "users : $users";
foreach($queryResult in $queryResults){
Write-Output "session ID : $queryResult.sessionid";
}
Any suggestion how to read a session ids from the queryResult then logoff all the sessions.

You need to parse the output of quser (it's not a PS command so the output is a simple string) - I've done it this way so that you receive an object that's more useful:
$server = 'myserver'
# Get list of logged in users
$queryResults = quser /server:$server
# Parse the quser output and store results in a new object. Skip first line as that's just headers.
$UserList = $queryResults | Select-Object -Skip 1 -ErrorAction Stop | ForEach-Object {
# Split up the current line into its elements
$CurrentLine = $_.Trim() -Replace '\s+',' ' -Split '\s'
# Create a new object from all the line elements. If session is disconnected different fields will be selected
If ($CurrentLine[2] -eq 'Disc') {
$SearchResult = [pscustomobject]#{
UserName = $CurrentLine[0];
SessionName = $null;
Id = $CurrentLine[1];
State = $CurrentLine[2];
IdleTime = $CurrentLine[3];
LogonTime = $CurrentLine[4..($CurrentLine.GetUpperBound(0))] -join ' '
}
}
Else {
$SearchResult = [pscustomobject]#{
UserName = $CurrentLine[0];
SessionName = $CurrentLine[1];
Id = $CurrentLine[2];
State = $CurrentLine[3];
IdleTime = $CurrentLine[4];
LogonTime = $CurrentLine[5..($CurrentLine.GetUpperBound(0))] -join ' '
}
}
# Output the custom object (stores it in $UserList)
$SearchResult
}
# Display a list of users/states/Id
$UserList | Select-Object UserName, Id, State, IdleTime
# To logoff everyone, you can just loop through
#$UserList | ForEach-Object {
# logoff $_.Id
#}
# Or you could just logoff the disconnected users:
#$UserList | Where-Object {$_.State -eq 'Disc'} | ForEach-Object {
# logoff $_.Id
#}
