Question : sbs 2008 AD error / Server locking

I have an SBS2008 server which is having some kind of DNS or AD error which requires a reboot to clear. The symptoms that I am aware of are Exchange goes offline and RWW becomes unavailble. The server was rebooted before I actually saw it. Here are the relevant events from when the server went offline

Error      7/4/2010 2:11:33 PM      MSExchange Autodiscover      1      Web
Error      7/4/2010 2:11:20 PM      MSExchange ADAccess      2501      General

Error      7/4/2010 2:02:40 PM      GroupPolicy      1054      None
Error      7/4/2010 2:00:05 PM      GroupPolicy      1030      None

Also the DNS log is filled with the following error starting the next day

Error      12/28/2009 6:23:02 AM      DNS-Server-Service      4000      None

I will attach a document that has all the details from a random sampling of the reocurring events. These errors all repeat up until the server is rebooted then disappear. The server is up to date on all patches and SPs.

The main error seems to be that AD can no longer resolve the server until it is rebooted. I am thinking that the DNS service is failing but am not sure. Any thoughts on how to proceed?
