Contest: Why Is This Desktop Empty?

Citrix/Terminal Services/Remote Desktop Services
Published Aug 9, 2013

I just had a situation where I was facing an empty desktop with no way to logoff, start a program or do anything else. The only thing left to do was to log the session off from an admin session. This got me thinking: how many ways are there to create such a situation? I am writing down all the ways I know of and ask everybody to contribute. Can you come up with a way to end up with a completely empty desktop I and no one else thought of before?

This is what I am talking about:

Empty published desktop

My Solutions

Explorer Killed

If you kill Explorer and have no other graphical application running, you are left with a blank screen.

Please note that if the shell is not stopped manually but crashes instead, it is restarted by default. This is governed by the registry value AutoRestartShell.

Custom Shell Closed

You can specify a custom shell through the Group Policy setting Custom User Interface. Such a shell is run on top of the default background - and can be closed by pressing ALT+F4 or by clicking the red cross in the application’s upper right corner (if available). After closing the custom shell application all that remains is the background.

Nice Try, But Does Not Work

Configuring an Invalid Custom Shell

This is tempting, but the developers at Microsoft are not stupid enough to fall for this one: specifying a custom shell through group policy that does not exist; in other words, specifying something like kasjdfljskdf. If you do that, the regular shell (Explorer.exe, of course) will come up.

This article is part of a mini-series. You can find the other articles here. In the previous part of this series we saw how to determine the capacity of a server farm. This time we will look at how that capacity is utilized, in other words at farm load. As before we will do that for the four main components of a XenApp server separately: CPU, memory, storage and network.

Leaked Token Handles Preventing RDS Session ID Reuse

Leaked Token Handles Preventing RDS Session ID Reuse

A recent article on Microsoft’s Ask the Directory Services Team blog piqued my interest. It talks about how leaked access tokens prevent logon sessions to be freed when the user logs off. This wastes system resources that can only be reclaimed by rebooting. A symptom of this happening is that RDS session IDs are not reused.
