xenapp 6.0 blue screens

Hello, we just installed xenapp 6 fundamentals on a new windows 2008 r2 server and we have been having problems where users are getting blue screens when logging in to their published desktops. Their icons will not show up - just a blank screen. This only seems to happen in the morning. Once they are in, they are fine for the day. I have a feeling that it has to do with how they close out their session at night. Maybe they X out of the window instead of logging off their session. However, I still don't understand why this would result in a blue screen the next day. Instead I would think that would just allow them to jump right back in to the disconnected session the next day.

Usually I need to kill their session from the server and have them try several times and things are ok after that. On a separate note, we also have a Desktop Fullscreen App published to the client and this ALWAYS shows up with a blue screen no matter how many times we try.

OK, I've narrowed it down. For whatever reason, it appears to be the GPO that is doing it. If I unbind the lockdown GPO from the OU that I have my Citrix server in, nobody has this blank screen issue. My problem is, I have no idea why my lockdown GPO would cause this. All my gpo does is disable things like control panel, command prompt, etc. Any ideas on why this could be causing the blank screens?

I also did enable the timeout on disconnected sessinos but I'm not sure that is really going ot make a difference
Do you have any logon scripts as part of that GPO?
No, they are all executed via the individual user.

We actually tried creating a new GPO. Same result. It was even a very simple GPO - hardly anything defined within it.
Just a thought but have you seen the issue if the user does not have any printers assigned?
perhaps it a bad driver that blows up during the auto creation process.
But this only happens when a GPO is enforced.
