cannot resolve external web address internally on a sbserver

HI
I hope someone can help me here. I am not great at DNS on a SBS, but I have a strong suspicion that this is where our problem lies. On our local LAN we cannot resolve to our business website which sits on an external server on the Web. If I change to the dns on the client machine to something like google public dns, it resolves no problem at all, but then cant resolve any of our internal addresses. So how do I fix this or what should I do to our SBS 2011 server to make this happen?
many thanks

you have to add a forward lookup in DNS like 8.8.4.4 to get access to the outside.  Restart the dns server when you are done making this change

HI, I had a look at the dns manager and at the forwarders and there is already 2 enties in there for 8.8.8.8 and 8.8.4.4
Basically this has worked in the past year and all of a sudden we just miracolously have this issue.

Do your internal and external domains have the same name, by any chance?

Through research elsewhere, I discovered in the forwarders there was an address pointing at the local server and once I removed that it then worked.
