dns server
We are having trouble with our DNS. When I look at DNS on my win 2008 r2 server it shows that the forwarders are not resolving. I go into them and they say validating but it never happens. It seems like this issue comes and goes which makes less sense than why it is happening in the first place. Any info on where I should start to find out a solution?
The first thing I would run on the failing server at a command prompt is dcdiag .
Check for any failures

Re-adding the forwarders did the trick. Any ideas on why this might be happening?

This time re adding the forwarders did not work. Not sure if that is what it is. Nothing will validate again. Here is the weird part. I have noticed that this happens every day around 10AM. Any ideas with that piece of info?
I want you to go in to control panel >Administrative Tools> Task Scheduler .....check in there to see if anything out of the ordinary is launching at the time you have mentioned

Did some research on the topic and found out to look into the event viewer. Saw the shun word in there and went from there to find out it was a firewall issue.
Also try removing "use DNS root hints if forwarders are not available"
Will.
