We installed SBS 2003 in the office a few months ago.
Since then, Internet browsing is very slow. It's not a connection speed issue, because downloads a quick enough. The problem seems to be in resoving the DNS info.
I don't have a complete understanding of the DNS process. But I would prefer to use the DNS of my ISP instead of maintaining an internal DNS (which I don't know how to do).
As a test, I set the DNS of one of the client computers to the ISP's DNS and the browsing picked up speed immediately, but then it cause problems with logging on to the domain. It worked, but took forever.
Any help would be greatly appreciated!
