The error “server did not register with DCOM within the required timeout” is signaling that one or more DCOM (Distributed Component Object Model) software is failing to register itself in a reasonable period of time.
A DCOM software needs to register itself as a server of sorts so that other programs or machines can call on its functionality remotely. If it fails to register or if it doesn’t do it within the predetermined time frame, the “server did not register with DCOM within the required timeout” will be displayed in the Event Viewer.
