Hello,
I'm trying to repair the DNS on a Windows 2008 R2 Server that fails the command dcdiag /test:dns. How can I reset or repair this? Here is the following test results:


Directory Server Diagnosis


Performing initial setup:

   Trying to find home server...

   Home Server = LINFORD01

   * Identified AD Forest.
   Done gathering initial info.


Doing initial required tests

   
   Testing server: Default-First-Site-Name\LINFORD01

      Starting test: Connectivity

         The host 09db5bef-5e6e-4260-9da7-63d37a19eecb._msdcs.linford.com could

         not be resolved to an IP address. Check the DNS server, DHCP, server

         name, etc.
