Domain Controller Diagnostic Errors on SBS 2008

Got a strange one here.

I received a report that one of our client's server is beginning to have dc/AD errors.

I rand a dcdiag and attached the results.  There is no RODC in the environment, but what really has me scratching my head are the 0xC0002719 and 0x40000004 event IDs.

I also did a dcdiag /test:dns and attached the results as well.

I did some checking online but couldn't really find anything that looked like it would address this issue.

The clients don't seem to be impacted by this but the number of entries has increases over the past few days.

The server is SBS 2008.

This is a long-standing client, so what I'm looking for are step-by-step instructions on troubleshooting and resolving this issue.  Thank you.

Thanks for the reply.

Could you please provide me the steps to fix these permissions?  

I want to be able to go in there and get this right the first time.

Thank you.

Ok.  Took your advice and looked in the Event logs.  I'm seeing tons of DCOM 10009 errors.

I followed KB957713 and changed the firewall GPO.  Will see if that does anything.
