Servers Can't Resolve Own Hostnames or Network
Got a rather puzzling and urgent issue. On Wednesday night we had a powercut which took out our Primary Domain Controller (win2k8r2). We're back up and running on the secondary server (now primary) running server 2003. We also have a new win 2k8 r2 server back up with the same configuration as before but this has for now been left as a secondary dc. It has the exact same setup as before.
We have a fair few servers but we are only having issues with 2 of them, both running win 2k8 r2, one running our SQL server and the other our Exchange 2010 server. Both of these servers have gone mad and can't resolve any hostnames including it's own or even localhost! On the exchange server I've tried to reset the TCP/IP stack and had a specialist looking at it too. Under nslookup it says Default Server: Unknown. Because of the hostname resolution issues the servers cant talk to AD or the internet which is obviously stopping both sql and exchange from starting back up.
Wondered if anyone else had come across this and might help point us in the right direction?
