Zone Not Loaded by DNS Server

Over the weekend my Windows Server 2008R2 installed 10 updates from Windows and now my DNS Forward Lookup Zone for YAJASSI01.local is not functioning.  I have tried running DCDiag /test:dns and it give the error that "SERVER failed test Connectivity".  I have look at setting in the firewall as it sujested and I even set the firewall to all all Incoming connections and restarted the server with the same errors.  This is a single server setup running AD, DNS and DHCP.
AD Domain Services shows now errors but DNS is showing Warning 4521 and Errors 4004 and 4015.

Hi,

Can you run a AD integrity check and make sure that the AD database is fine? this will be the command

ntdsutil

ntdsutil: activate instance ntds

ntdsutil: files

file maintenance: integrity

Let us know the outcome. Also, make sure that the DNS zone didn't changed to some thing else rather than AD Integrated Zone.

Hi,

Jet Database error. This is clear that the AD database on this DC has got corrupted. Either perform offline fragmentation or restore it from the latest working backup. Not sure how long the issue were there, untill you don't know when was the good backup, it's no use of restore.

Some times offline defragmention works but the issue may occur afterwards.

I would suggest to perform an Integrity check on all the DC's and make sure all are fine. Then, perform Offline defragmantation.

If that does't work, only way would be dcpromo in and out (demote and promote).

Please let us know If you need further assistance.
