have you created AD integrated Reverse lookup zone for all subnets in which all Domain Controllers residing?
I think they are missing ?
Just check if you have them, if not please create them, run "Ipconfig /registerdns" on all domain controllers, allow some time for replication and then run DNS test again and let me know please.

Thanks Mahesh and Sandesh,

when I checked the command output, i see a section like this:
_____________________________________________________________________
TEST: Basic (Basc)
Error: No WMI connectivity
[Error details:0x80070005 <Type: HRESULT - Facility: Win32, Description: Access is denied.>- Connection to WMI server failed]
____________________________________________________________________________

this is coming everytime , when I run this command from PDC and it is checking to all other ADCs.

Is it something that I need to be worried?

It seems to be WMI issue check this http://social.technet.microsoft.com/Forums/windowsserver/en-US/4f33837b-1cb1-4648-85b1-3ba87cbfe93e/wmi-remote-access-denied?forum=winserverManagement

Checked that wmi is not corrupted.Run wmic pagefile output in cmd.

Thanks Sandesh,

meanwhile this is the side-by-side comparison of AD sites and DNS Reverselookup zones.
AD-DNSsites
Do they look alright?

Hi Sandesh/Mahesh,

i checked the link that you suggested for WMI and find everything is alright.

What next?

By the way, not sure if this is relevant, all these DCs are in windows 2003 platform.

Can you pl check on all domain controllers advanced TCP/IP properties \ DNS tab for below.
ensure that "Append Primary and connection specific dns suffixes" radio button is selected
Ensure that "Append parent suffixes of primary dns suffix" checkbox is selected
Ensure that "register this connection addresses in Dns" checkbox is selected
If there is any deviation in the above settings, its probably you will face name resolution and connectivity issues
Also check for any false \ wrong forwarder entry exists on all dns servers forwarder tab..
Also check if you are able to replicate AD through AD sites and services without any issue please
Thanks
