MFCOM What? Yeah, not for everybody but a good way to learn the ins and outs of how your farm works. Here is a great powershell example on how to use the very powerfull citrix mfcom to attach to your farm, enumerate users and their session state and then reset any disconnected sessions.

On the flip side, one would perhaps be inclined to say. “Doh, what about setting a local group policy, or even better how about group policy?” Well, most of us do like to configure some type of policy, either locally or from a domain perspective. But I would also say – why not also have a little fun with some powershell? Programmatically, you can kick out users in a disconnected state – what’s cooler than that? Seriously?

If this script isn’t power than you may have to be one of the many that hit this site, grab a script or two, and then bounce in less than 10 seconds.

The following powershell example will use Citrix MFCOM and allow you to quickly enumerate user sessions in a disconnected state and disconnect them gracefully.

 

Citrix MFCOM powershell - Enumerate farm user state and disconnenect "disconnected user sessions".

 

# Powershell script to locate disconnected users, log them off and iterate through all sessions to find users # in a disconnected state. while ($sessCount -ge 0) { $MetaframeServers = $myFarm.Servers | Sort-Object -property ServerName | ? { $_.ServerName -like $citrixserver} $sessCount = $MetaframeServers.SessionCount Write-Host "Current session Count = $sessCount on $XenAppServerName" -ForegroundColor White if ($sessCount -eq 0) { Write-Host "$XenAppServerName is free of users" -ForegroundColor White break } else { $disconnected = @() Write-Host "Checking for disconnected users on $XenAppServername" -ForegroundColor White $disconnected = @($myfarm.Sessions | Where-Object {$_.SessionState -eq 5 -and $_.ServerName -eq $citrixserver}) if ($disconnected[0] -eq $null) { Write-Host "There are no currently disconnected sessions on $XenAppServerName" -ForegroundColor White Write-Host "Waiting 10 minutes" -ForegroundColor Red Start-Sleep -Seconds 600 } else { Write-host "Processing: Logging off disconnected users from $XenAppServerName" -ForegroundColor White $i = 0 foreach ($user in $disconnected) { $namedUser = $disconnected[$i].Username write-host "Logging off $namedUser" -ForegroundColor White $user.Logoff($false) $sessCount-- $i++ } } } }

Update... So people are looking at these examples! I'm impressed.

jpmorgan chase & co.	00:06:19	Not a bad term to be searching for "citrix and mfcom powershell". This seems to be somewhat popular around here as people are updating their farms from 4.5 - to xenapp 5 and even 6.
