xenapp error documentation

 
It's probably time to start documenting all of the random issues our Citrix end users encounter. Most of which can be quickly fixed, while others need to be investigated more thoroughly. This section will be quickly expanded as any issues in the new XenApp 4.5 farm come into play, and windows 7 is deployed to the environment.  
 
Note: You'll probably find these errors all over the place, we just wanted to document them for our own sake. Please add any commentary where necessary (for our 5 readers).
