DNS is causing my Domain Controller (Win2003R2) to hang on reboot. It

freezes on "Preparing Network Connections". To determine it was DNS, I

booted into Safe mode and disabled DHCP and DNS. The server booted normally

and I was able to log in. I then enabled DHCP and rebooted server and the

server booted normally. After I logged in, I then changed the DNS service to

manual and started the service and it started successfully and my forward and

reverse zones came up (active directory integrated) and all AD errors were

cleared on this particular server (I have a total of 4 DCs among 3 different

sites).

 

Problems started a couple of weeks ago, when after a reboot, DHCP and DNS

were not working. I had to manually start DHCP and although DNS was running,

the zones were gone. After I restarted DNS, the zones reappeared and all was

fine. The next week DHCP was fine, but again, the zones in DNS disappeared

until I restarted the service. Now this week, DNS won't even allow the

server to boot. Once DNS is started, replication appears to be working just

fine between my sites, and my workstations and servers are happy.

 

Any suggestions on fixing the startup issue when DNS is set to automatic?

Seeing as though this is a DC, I probably can't just uninstall and reinstall

DNS, can I? I will probably be running dcdiag to help confirm things are

okay between all the DCs, but any other suggestions would be helpful if you

have them.

 

I'm just not sure why the DNS service is freezing my server upon startup.

 

Thank you!

Re: DNS service causing DC to hang on reboot

 

There may be an issue with the recent DNS patches conflicting with other

network services.

Re: DNS service causing DC to hang on reboot

 

Well, I'm looking into this, but I checked in Add/Remove programs and I'm not

seeing that the security update 953230 was installed on this particular

server. I did however install some updates from July a few weeks ago (I was

a little behind). Thank you for the info. Hopefully this turns out to be

the problem and I can fix it according to these articles.

Re: DNS service causing DC to hang on reboot

 

I think I might have found the update causing the problem:

 

Microsoft Security Bulletin MS08-020 – Important

Vulnerability in DNS Client Could Allow Spoofing (945553)

 

This is one of the 5 updates I installed on this particular server on 9/3,

and the only one relating to DNS. I do have this update on another Domain

Controller and the DNS service however is not doing the same thing. That

server boots up just fine. But, perhaps it is a start to figuring out this

issue. Maybe I will remove the update and see if that fixes the problem...

Re: DNS service causing DC to hang on reboot

 

If it fixes the problem you would have to find out what port DNS is

clobbering then make an exception for it. It is important to install the DNS

patches. They do cause some problems on some systems but the problems can be

worked around. It just takes some work :-)

Re: DNS service causing DC to hang on reboot

 

I attempted to reserve port 53, but I realized that probably wouldn't work

because random ports start at 1024, so 53 shouldn't be affected. I set the

DNS server service back to automatic and it hung again on "Preparing Network

Connections". Honestly, I'm not sure what else to try at all. I can attempt

to remove my latest Windows patches, but if I remove 945553, I have to also

remove 948590 and 948881 because they appear tied to 945553. I really don't

want to call Microsoft and open a case #, but I'm not sure what else could

have hosed my DNS server service. Any other ideas? Anyone?

Re: DNS service causing DC to hang on reboot

 

Removed Updates KB948881, KB948590 and KB945553 (in that order) and then set

my DNS server service to Automatic. Rebooted, and it booted up successfully

and did not hang. Next, reinstalled KB948590 and boot was successful. Next,

installed KB948881, and boot was successful. Finally, reapplied KB945553

(specific DNS update), which I downloaded manually and installed rather than

use WSUS or Microsofts Update page, and lo and behold, my server won't boot.

So, it's definitely the KB945553 update causing my problem. I'm going to

remove it and keep the other 2 and then contact Microsoft in the

morning...I'm not sure what more I can do about how to fix it if the update

is causing DNS to not work properly during startup...

Re: DNS service causing DC to hang on reboot

 

Are there any errors in the event logs? I would suspect that the DNS service

may indirectly be causing the problem. My suspicion is that DNS is using a

port that another service or program needs causing that process to fail. If

you can figure out what that process is then reserve the ports it needs this

may fix the problem. The again it may be your system is just not compatible

with KB945553.

Re: DNS service causing DC to hang on reboot

 

I removed the update again and put DNS back to automatic and it hung

again...I think I have to get rid of the KillBits update, KB948881, too. How

would I figure out what port DNS might be using? I have absolutely no idea

how to do that.

Re: DNS service causing DC to hang on reboot

 

By the way - no error messages are showing up at all, probably because it

can't get booted up all the way...

Re: DNS service causing DC to hang on reboot

 

Well, now it won't boot up correctly and I have all 3 updates removed. Maybe

I should have removed them in the original order like I did the first time, I

don't know. I am going to have to put my DNS server back to Manual, I think

, until I can figure this out. This is SO frustrating!!! Gosh, I hope that

works at least...
