I have one user having issues opening an application online.  I can log into the xenapp server no problem.  It get to mapping drives and group policy and the Reciever disappears.  I looked in the event logs and we have event ID 6000 to 6005.  Any help would be appreciated.

what do you mean by that have the user logon directly to that server?

You looked at the event viewer of which machine? That is, are the mentioned event IDs 6000 to 6005 related to the client machine or the XenApp?

What is the OS?

Moreover, what are the error messages within these event IDs? What is the source of the errors?

Usually all the errors of event IDs ranging from 6000 to 6005 would indicate one of the following:
1. Corrupted registry
2. Running out of resources (high CPU and Memory utilization)
3. Service failing to start

Based on the description, there are no app resources available to that user.  The app attempts to launch, but then can't because it isn't available.

Most likely, this is an issue with load balancing.  Look at both the server and app load evaluator that would be applicable to determine whether a server resource is available. Typically, app load evaluators aren't applied, but that could be your culprit.

Run a qfarm /ltload to see whether resources are indeed available.  Health Monitoring and Recovery automatically pulls 10% of your servers out of load balancing if any of the metrics are exceeded in XA 6 and earlier (fixed in XA6.5).  So, it's quite possible that a server that you think should be serving the app isn't doing so.

1. Is it happening only to one user?
2. If yes, ask the user to try from a different PC/laptop to make sure printer recreations aren't creating problems.
3. If same, then compare the application permission of a working user and non-working user. Check the registry permission.
4. For testing purpose, add that user to local admin of that server and publish the app only on that server and check.
5. Also compare the GPO settings of working and non-working user.

I found the problem the problem was with Group Policy that was mapping a drive and not use anymore.  It looked like it was timing out once I removed the Group policy it worked.

Group Policy was the problem.  It was just a mapped drive policy and removing it resolved the issue.
