I installed a new Win2008 Server last week (new forest, etc.).  This morning we had lots of connectivity issues that seem to be resolving themselves one-by-one, slowly.  Dcdiag reports: "The host xxx.local could not be resolved to an IP address.  Check the DNS server, DHCP, server name, etc.  Got error while checking LDAP and RPC connectivity.  Please check your firewall settings."  The remaining tests passed.  Can anyone walk me through this stuff?  Thanks...

Well, I believe I've found the culprit.  When I configured the DC I gave it a static IP and pointed the workstations' DNS there.  After posting my question I noticed it had reverted to dynamic.  So now my question is, how could that happen?

I would update your network card drivers and firmware.

Run sfc /scannow to make sure no corruption in system files.

You won't really know exactly what happened since this could have been a user mistake as well.

We turned the problem over to Dell's server support folks, who helped us remove the DNS role completely and reinstall it.  In the process, while disconnecting and reconnected all the stuff plugged into the router and switch, that a Dlink DAP-1525 wireless booster with 4-port switch device was clobbering the DNS each time it was plugged in.  We replaced it with a standard gigabit switch, and DNS settled right down.  I suspect it was the Dlink device all along.

I don't think it's likely that the real answer would have emerged from our interaction.  But I'm most appreciative of all the experts' assistance each time I have a problem.
