DCOM Error - Event ID 10009

We get the following error several times every day in one of our 2003 Servers.

The server is used as a Windows Update Server and an IP Monitor.

System Log

Go to this registry key and find your listed DCOM protocols:


HKLM\Software\Microsoft\RPC


Paste them here. They will be something like:


ncacn_ip_tcp
ncacn_spx
ncacn_nb_nb
ncacn_nb_ipx


It's always the same IP(s), or different ones that show up in the log?

Sorry - also, is this happening when your IP monitor program attempts to communicate with these devices?
