5719 error, but everything sees to be working?

Greetings,

I have one DC in my domain that is posting an Event 5719 error several times a day stating"

"This computer was not able to set up a secure session with a domain controller in domain MPC due to the following:
The RPC server is unavailable."

This is the only domain controller that's throwing an error and it is consistently a specific 2003 server it is referenceing.

I can ping domain and open admin snap-ins over the network. Do I need to increase the logging to see
specifically what it's complaining about? Or am I missing something else?

Here is the ipconfig of computer referenced:

I've been googling this event for awhile and haven't found anything that I think points in the right direction. Any guidance would be greatly appreciated. Thanks.
