Hi Everyone, I am getting the following error message in the application event log on both of our clustered exchange servers:Exchange A: Process EMSMTA.EXE (PID=2112). Topology Discovery failed, error 0x80040952 Exchange B: Process EMSMTA.EXE (PID=2112). Topology Discovery failed, error 0x8004095 Any Suggestions, Jeff

Hi Jeff, What version of Exchange? If you don't have Exchange 5.5 or x.400 connectors, you can probably safely ignore this error. However, here is an article that might be helpful: http://support.microsoft.com/kb/821833/ Thanks, Jim

Hi, Does this error cause any work stoppage? Thanks Allen
