Can anyone here please share some way to fix the DNS Delegation
test failure ?
TEST: Delegations (Del)
Error: DNS server: PRODDC26-VM.MyDomain.com IP:<Unavailable> [Missing glue A record]
Because when I execute the command dcdiag /test:DNS
my newly deployed and existing domain controller, it is FAIL on the Delegation test only.
Ping is succesful for PRODDC26-VM (server still exist and running as another DC/GC & DNS in another AD site).
There is A record in the DNS forward lookup domain MyDomain.com for PRODDC26-VM
There is another NS record under the "greyed out" _msdcs folder with NS (same as parent folder) static pointing to PRODDC26-VM.MyDomain.com
_msdcs --> greyed out.
What is this delegation is for and can I safely delete it ? What's the impact ?
