Automatically switch to secondary DNS server when primary DNS server is down
Posted on 2006-06-22
I have two servers, one SBS 2K3 Premium, and one Win Server 2K3 Std edition. Both servers are domain controllers.
The SBS is/was the primary DNS server, and the Win Server is the secondary DNS server. All the DNS settings are replicating properly.
Yesterday I had to take the SBS server offline to rebuild, so I assumed the secondary server would take over the DNS but it did not. If I manually point our workstations to the secondary DNS server, everything works fine. However, they do not automatically detect it. They just keep searching for the primary DNS server?
I'm pretty sure the reverse lookup zone is setup correctly, nslookup, ping, etc have no problems.
How can I change it so the secondary DNS server is detected if the primary DNS server goes down?
Thanks for your time,
