agree with @mnkhawaja

first step in DNS diagnosis should be running nslookup to find out which DNS server is used by default and what it's responses are to the domains you are having trouble with. compare the results to a machine that doesn't have a problem (even if it's one at home or another location) to see what doesn't match up.

It sounds like you have not set up a forwarder. As part of your nslookup enable debug options so that you can get a more verbose view of what is going on.

c:\> nslookup
> set type=a
> set d2
> google.com

If you're DNS server is setup correctly as far as forwarders/hints you should see the query go as follows:

1. google.com.internal.yourdomain.local (error will be NXDOMAIN)
2. google.com.yourdomain.local (error will be NXDOMAIN)
3. google.com (resolves via external DNS - at least it should)
