Windows Process Activation Service (WAS) did not register protocol %1, because WAS cannot register a protocol when there are listener channels from a previous listener adapter connection for the protocol. This may occur because you have worker processes running under debuggers and because orphaning may not be turned on. In this condition, WAS can detect the stop of a listener adapter, but it cannot kill the processes that contain listener channels. For this reason, WAS must wait for an admin to end these processes before a new listener adapter can connect. The data field contains the error number.
