BleepingComputer.com: Citrix

Does anyone here know anything about Citrix?
Here is the problem. All the PC's in my network are running XP Pro SP2. THey connect through Citrix to terminal servers hosting some business critical applications. There have bee random problems with some PC's getting errors when trying to run the applications that their network connection has been interrupted and the apps don't load. These errors are always happening only on the client PC and are not profile based since the user is able to launch the apps from another PC. I have tried the Citrix forums on www.citrix.com but there are no solutions there. The only solution that I have been able to get to work with any consistency is to re-image the PC that has the issue. I was hoping that maybe someone here might have a better solution. This problem is driving me
