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.

Update:

I think I've deteremined this is a DNS issue. My nic with an external address has an external dns. If I add a FQDN of my DC in my hosts file using the internal IP address, everything works fine.

I'm wondering if an easier fix would be to put my internal DNS ip on the external NIC as the first source. Would that be ok, or would it create other risks/concerns?

Thank you for your time.
