Specified Domain Does Not Exist or Could Not Be Contacted

Problem: Suddenly this morning after a reboot of domain controller no clients can access Outlook or the Internet.

It seems to be DNS related but I'm very confused.

The servers NIC is configured to a static IP.
The primary DNS server is the servers IP address.
In DNS, there are two forwarders to opendns.org's dns service.
At the server I cannot access any external website but I can access the Outlook Web Access page using its local address.

No clients can access or even ping the server address.

To troubleshoot the problem, on my client I added a secondary DNS server to match opendns.org's address (208.67.222.222). Once I did that I could access the web no problem on my computer.

On my computer if I do an "nslookup google.com" it times out trying to query my DC (primary dns) but then works fine after querying the secondary dns.

To test the server, I tried dumbing it down, I...
- disabled the DNS server service
- Changed my primary DNS server from itself to the opendns.org address
- did an ipconfg/flush dns
- disabled and enabled the local NIC

I figured that since the above settings worked on a client , it should work on server at least just to test DNS, but it still fails exactly the same way. The server itself doesnt seem capable of querying any external DNS servers. I tried a few different DNS servers- they all fail.

I've called Microsoft support, but Im hoping EE can save me before they call me back.

Right now we're dead in the water.

by the way, nslookups of any local domain computers work fine at the server, just external sites fail.

Were there any Windows updates or A/V updates applied to the server at about the time the problem began?

MrLoonandB,
I did notice and was a little concerned about an event viewer log listed below

Event Type: error
Source: crypt32
ID: 11
Description: Successfull auto-update retrieval of third-party root list sequence number from:
<http://download.windowsupdate.com/msdownload/update/v3/static/trustedr/en/authrootseq.txt>

When I saw that, the first thing I checked was an nslookup of windowsupdate.com (this was before reboot that totally brought down server) and the results were 208.111.160.135. I checked that IP on ARIN.NET and was surprised to not see Microsoft as the owner- instead it was "Limelight Networks". I dont know if thats ok or not, but did alarm me.

kukno, I'm not sure what you mean.

Check in add/remove programs and see if the update successfully installed. If so, might suggest uninstalling and rebooting the machine. If that corrects the issue, we can move forward on finding the problem with the update.

I mean routing. Does your server know the default gateway on the network?

Just post the output of "route print" (in a DOS box).

I think I figured this out.

The SysVol folder on the server had inadequate permissions. After adding "Authenticated Users" with read and execute permissions, all seems to be ok.

Of course, Microsoft calls me back just after I fix it  =)

Thanks for the assistance.
