I've just promoted 2x new Win2012 R2 AD DC with integrated DNS server to replace the existing Physical server 2008 R2 domain controller.
However, when I issue the test dcdiag/test:DNS
in both of my new 2012 R2 domain controller, it returns failed:
Auth Basc Forw Del Dyn RReg Ext
PASS PASS FAIL FAIL PASS PASS n/a
The error is in Delegation and the Forwarding.
While the existing old server all successfully PASSED, I can also ping to one of my forwarders that is 18.104.22.168.
The new servers cannot even ping 22.214.171.124
Any help would be greatly appreciated.
