Is there a solution to remove the client from a pc. I have reinstalled the ZCMserver and the client tells me that he is already registered (in the GUI). When i try to do a zac -ur the I have a message that the client is not registerd. A ZAC -reg tells met that the pc is registerd. A unistall from the client tells me that this is "not authorised".

This is the chicken and egg problem.

How can i now remove the client?
