Hi All,

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 8.8.8.8.
The new servers cannot even ping 8.8.8.8

Any help would be greatly appreciated.

Thanks,
