I think my DNS is sick

Our ISP has recently changed their DNS numbers. Since their change, web browsing has been very troublesome. The page will eventually load but it may take once or five tries before it does. Is there something I need to do on our network for name resolution. Our windows domain controller also serves as our internal dns server.

Change the forwarders on your DNS.
I've seen this happen and as I recall it's when you may have entered the ISP addresses manually somewhere.  Even if they are supposed to still be "good", they might not always be.  That and any cache.  So, reboot everything would be the simple fix for that.

How do you do this?
In the DNS snapin rt click on the server in question, and go to Properties:
Forwarders Tab
Add or Remove/update the DNS addresses from your ISP.

Does your ISP require you to use their DNS servers? The best option if not would be to not use forwarders at all and rely on the root hints. This would prevent this problem from occurring again.

I think we have a winner. Thanks for the advice!!!
You might also consider changing to Google's public DNS servers, 8.8.8.8 and 8.8.4.4.  They have some pretty beefy DNS security procedures in place.  You can do this in the DNS Manager on the domain controller.  The exact steps vary depending on what version of Win server you have.
