The DCOM Server Process Launcher service runs as LocalSystem in a shared process. It shares the executable file with other services. If the DCOM Server Process Launcher fails to load or initialize, the error is recorded into the Event Log. Windows 7 startup should proceed, but a message box is displayed informing you that the DcomLaunch service has failed to start.
If the DCOM Server Process Launcher is stopped, the Remote Procedure Call (RPC) fails to start and initialize.
