I'm using Windows SBS 2011 and I get an error message when trying to add a DNS Forwarder.  It just says "unknown error occured".

I tried to disabled Enhanced DNS but that didn't make any difference.

Anything in the event log?   That's a pretty vague error!!  Can you take a screenshot of what it is you're trying to submit when you get the error?
You are logged on with an admin account, right?

no errors in the Event viewer.  I am logged in as Administrator.  

I've attached the screen shot.

Ok -

Looks to me that the server you're trying to use is not allowing the validataion  (I get the same error), but it seems to work as a DNS server anyway..

Have you tried to just ignore the error and use it anyway?

I'm not sure if you have to use THAT DNS server or not, but you might check with your ISP for what their forwarders are, or use another public one, like google's 8.8.8.8 if that's an option.

At the very least, can you try to put in 8.8.8.8 to see if you get the same validation error?

You were right, I ended up using different DNS servers and that worked just fine.  I'm now using the ISPs DNS servers without any problems.

I take it there must be some security policies in place that are not allowing me to use them.  

I do have another DNS issue I'm trying to resolve but I'll ask a new question.
