DNS Corect Setup on Active Directory
Posted on 2009-05-08
I recently started experiencing some problems after one of my DNS server crashed. I have a network with 500 worskstations and I have 8 DC servers running at each of my subnets.
When my Primary DC crashed at my main site, all workstations stoped resolving when trying to get to my internet.
All of our internet traffic goes out from our main site and since that DC had the Forward Pointers to external DNS all the rest of my DNS servers could not rsolve for them
All my DNS are active-directory integrated.
My question is ; do I have to setup Forwarders on all my DNS to use external ISP dns?
Also I noticed that even thought all my workstations had a secondary DNS they did not use it to resolve.
Any help is greatly appreciated
