Major DNS issue
Posted on May 30th, 2009 No commentsHello,
I came into the office and rebooted one of our member servers and noticed that on reboot it said a service didn’t start. When I started looking into the errors it pointed me back to our primary DC. When I go into DNS I don’t see anything under the forward or reverse lookup zones. They are empty. Any and all help would be MUCH appreciated. Here is the results of running dcdiag /test:dns (LEWISDC1 is the server in question, this was ran on this server)

0000: 2d 23 00 00 -#..Well after shelling out $515.00 to Microsoft last night the issue is fixed… They worked about 2 1/2 hours on it and I didn’t even need to rebuild anything. They were able to use ASDI Edit to make some edits to the AD object of this server and then reset some of the Kereros settings and all is well now..
Not sure on awarding any points on this since it seemed like the general concensus here was to blow the server away and rebuild/restore it. Which by the way, I did take the server down before I called MS and did an AD restore of the system state and that seemed to help a little but it was still very messed up in thinking it was a Domain Computer instead of a Domain Controller. It also was holding 3 of the FSMO roles and I was unable to transfer them also.. I had tried that before the MS call as well. Over all I was really impressed with the expertise of the MS support engineer though, very good…
So with all that said if the Administrator wants to award points then I will let it be his call. Thanks anyway for the responses.
