DCDIAG - Azure VM DC Failing Advertising Test

Seth Holek 51

I am trying to migrate DC's to DFS, but I cannot prep an Azure VM DC. I believe the issue to be with the server failing to advertise. Thoughts?

Directory Server Diagnosis

Performing initial setup:
   Trying to find home server...
   Home Server = VIT-2016
   * Identified AD Forest.
   Done gathering initial info.

Doing initial required tests

   Testing server: WindowsAzure\VIT-2016
      Starting test: Connectivity
         ......................... VIT-2016 passed test Connectivity

Doing primary tests

   Testing server: WindowsAzure\VIT-2016
      Starting test: Advertising
         Warning: DsGetDcName returned information for \\SIT-DC12.xxxxx.local, when we were trying to reach
         VIT-2016.
         SERVER IS NOT RESPONDING or IS NOT CONSIDERED SUITABLE.
         ......................... VIT-2016 failed test Advertising
      Starting test: FrsEvent

I'd check the domain controller has own static ip address plus loopback (127.0.0.1) listed for DNS and no others such as router or public DNS.

Thanks for the suggestion, but don't think that is going to work, as this DC is not a DNS server.
