Do not mind your english at all.... glad with your reply :smileygrin:

Will investigate that, but I don't think it's a problem with the response time of the domain controller.

From what I can understand from the reports is as that a user gets a desktop assigned from which an other user has disconnected. It's as if the broker is no longer aware that a user is logged on. That should not have anything to do with domain controller response time.

As a workaround for the problem we are thinking of logging of a user as soon he/she logs off. But being able to reconnect to a disconnected desktop has been a big advantage for users. We would rather not loose this advantage.
