2008 R2 DNS keeps failing?

My new install of Server 2008 DNS services fails every 3 or 4 days?  nslookup finds correct info and I can ping dns from workstations.

Please help

When I run trouble shooter It says that the DNS server I am trying to use is incorrect or doesnt exist. but I see it running without errors in its event logs

The DNS is on the DC as well as the DHCP.  I have removed the role and then added it back but I am not getting to the outside.  I also ran a hotfix I read in another string but it has not helped either.

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

I fail to see problem. Looking up loopback makes no sense to me (=host file) as a test though.

Please elaborate!

Do run this on the DC gain, this time:
nslookup 10.0.1.10 127.0.0.1

Open in new window

You should get reverse responses, like this:
Server:		127.0.0.1
Address:	127.0.0.1#53

10.1.0.10.in-addr.arpa	name = server01.mbo.local.

Open in new window

I will run those commands and report back

But this is completely fine.
Do you have any other problems with DNS then with DNS troubleshooter?

I just cant get to the outside world.   while poking around I ran best practices analyzer and it states a couple of errors.

Root hints - All root hints failed an NS query.  
When I look at the root hints it has a bunch of IP's that dont belong to me in there.  Could this be the cause?  And can I remove them without to much worry?

Just FYI Everything internal works fine

Daniel HelgenbergerCommented:
Yes, the root hints. You can put them in, but this is not very efficient. They are very slow and are some last resort lookup.

You just might forgot to put in forwarders.

Just forward your DNS to Googles public DNS servers, 8.8.8.8 and 8.8.4.4
These are clustered; meaning fast and extremely reliable IMHO. If you forward to these and maybe a third DNS from your ISP you will never need the roots.

Ok I added those as the forwarder in the DNS properties but still no luck to the outside it say the are unable to resolve

On your Server, do this:
nslookup google.com 8.8.8.8

Open in new window

It came back as unknown.  But after throwing a fit I learned someone had run a patch cable from another modem to the same switch causing my issue!

THANKS FOR ALL YOUR HELP!  Believe it or not I learned quite a bit from this thanks!
