Recently we had a WIN Agent (V11.2.4) to be wiped out of our System. The Win Server was rebootet but the Agent still showing as active in System Overview. Trying QUIT out of System overview was answered with "Process not found or not active."
Statistics & Last report told us it was stopped 2 days before, what was correct.
After hours playing around with that damned agent (we restarted the CP it was hooked to as well) our last try was restarting the PWP.
THAT did the trick, we were able to stp the agent and delete it from Clt 0.
