I have been seeing these errors show up in the server logs recently. I have run dcdiag and all the tests pass, on running netdiag the DNS test fails saying can't find an authoritative DNS server for our server. It says it is not correctly registered on server 0.0.0.0. Running IPconfig /all shows the DNS server with the correct IP address. Both the DNS server and the DC are the same server. Running netdiag /fix does not work it can't register with the DNS server. I have attached a DNSlint report which may help. Thanks.

There is just the one Network interface (Local Area Connection). The error message is "Windows cannot obtain the domain controller name for your computer network. (An unexpected network error occoured. ). Group Policy processing aborted. "
Thanks.

It almost sounds like your TCP stack is corrupt.
Have you tried resetting it?
netsh int ip reset c:\resetlog.txt
Of course, after you do that, you'd have to reset up your IP config/DNS/WINS, etc ...
Your help has saved me hundreds of hours of internet surfing.

I have reset the TCP stack but am still receiving the errors. I have attached the relevant output from netdiag /fix. The DNS is definitely registered and running (all the client are able to perform DNS lookups). netdiag.txt

Hmm. the 0.0.0.0 DNS looks weird.
A couple of additional items:
- Do you have IPv6 enabled on the server?
- Can you post your full ipconfig /all (unedited) ?
- Do you have the forward and reverse lookups for your server?
- Have you checked the values of your _dc,_SRV,_GC,_kerberos , etc ... do they all look ok ?

IPv6 is not installed on the server.
The full output of ipconfig is:
Windows IP Configuration
I far as I can tell all the records in the DNS are correct. I've expanded all the branches and can't see anything that looks wrong. I'm not a DNS expert so there may be something missing, but forward and reverser lookup zones are listed with a correct entry below each.
Unlimited question asking, solutions, articles and more.

Still very odd.
Alright, moving on :)
Would you please post the one line of the result from:
ping barnabas and ping barnabas.stbk.org.uk
Also, could you share the result of
netdiag /test:DNS /v > c:\dnstestresult.txt
There's gotta be a pointer somewhere that gets us to an explanation. Most of my research was pointed to having IPv6 enabled and misconfigured, but since you state that it's disabled in your case, then I'm assuming there's a different problem.
By the way , is there a reason your DNS search list is searching in the TLD as one of the search list options? do you have DNS devolution enabled?
Can you check your DNS search list, and make sure that you only have stbk.org.uk in there?
(I'm pretty sure that .org.uk wouldn't do you any good in any situation)

I noticed that you have an AMD processor. And in researching, a lot of people are mentioning that there is something with the processor drivers that cause this.
Another symptom which I also noticed in your pings, is that you're getting some negative values on the ping. This is not necessarily a bad thing, but could also have something to do with the processor driver.
I know it's out of left field, but your configuration on the server looks pretty good as far as I can tell.
In this case, I was just going back to the original error that you are getting (UserEnv 1054).
