I have just had a strange problem, when an individual user  tried to launch any published application another server desktop session was initiated with the below message, resetting the users profiles etc made no difference.


It turned out the cause of the problem was on the “Environment tab” for the users AD account the option “Start the following program at logon” was ticked, even though there was no program specified it was enough to stop the published application loading as it should.

Un-ticking the option instantly fixed the problem 🙂
