Windows 2012 R2 Server Joins SBS 2003 Domain But then Fails to Find It on Reboot

Greetings!

We're adding a new Win 2012 R2 member server to an existing SBS 2003 domain. It successfully joins the domain, but on successive reboots fails to id the network as a domain network and so it defaults to a "Public" network and fails to authenticate to the DC. On each reboot, in the Event Viewer, the NIC shows that it is "disconnected" and then 6 seconds later Netlogon reports that it can't find a DC.  We've experimented with adding "Netman" as a service that Netlogon depends on, but have not had any luck. The NIC has the newest available driver.  

Any advice?

The fact that NLA is reverting back to a public network os extremely concerning. I'd be very suspicious of a significant hardware issue in such circumstances.

For the record, it turned out to be missing records in DNS.  All of the Resource Records were missing.  Once I forced the SBS server to register itself in DNS they were recreated and all was right in the domain.

Thanks for your response!
