WIN2008 R2 DNS ACCESS DENIED

The AD 2008r2 PDC hard drive is down, and DNS cannot be opened after BDC transfers roles, and has the following log:

When the server had rebooted the network location had changed to Unauthenticated. When trying to access the DNS console I was getting an error saying Access Denied.

As shown in the figure:

DNS Access Denied

The DCDiag test failed, but Active Directory users and computers can be accessed.

The solution is as follows:

Run the following command and then restart to resolve the error:

Nltest / sc_change_pwd:domainname.local

PS:

Command Description:

Changes the password for the trust account of a domain that you specify. If you run nltest on a domain controller, and an explicit trust relationship exists, then nltest resets the password for the interdomain trust account. Otherwise, nltest changes the computer account password for the domain that you specify. You can use this parameter only for computers that are running Windows 2000 and later.

Once the server had rebooted the network location changed back to 'Domain' and DNS was accessible. All client machines was then able to access the server.

Comments on my blog have indicated that this fix also works with Server 2012 R2.
