Default Behavior
RPC Endpoint Mapper is a Win32 service. In Windows 7 it is starting automatically on the operating system startup. Then the RPC Endpoint Mapper service is running as NT AUTHORITY\NetworkService in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If RPC Endpoint Mapper fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the RpcEptMapper service is not running because of the error.
Dependencies
If RPC Endpoint Mapper is stopped, the Remote Procedure Call (RPC) service fails to start and initialize.
