I'm not going to go incredibly in depth yet unless you need me to. But anyway, I have a shop with 3 domain controllers. The primary has DNS, AD, and WINS. The two secondaries have just DNS and AD. Yesterday I pushed out a GPO setting that replaced one of the secondary servers with the new primary server. I changed the setting: Computer Config/Policies/Admin Templates/Network/DNSClient/DNSservers.
When I did this, some clients could not resolve network names using DNS only WINS. They all have the correct network settings local on the machine, but I'm assuming the GPO is overriding them. Once I changed the GPO back, everyone was OK.
My question is, how can I tell or set my domain to primary use DNS? I know I shouldn't need WINS, but we have it and that can't change right now unfortunately. Thank you for your help here.
