I looked at the root hints and it is pointing to itself. Since this is SBS 2003 and its the only DNS sever on this local network I presume the problem is the root hint is pointing to itself??   So if thats the case then and this is the only DNS server do I just remove the root hint all together??

Okay - all looks good apart from the Root Hints tab - I am attaching my Windows 2003 Root Hints screen dump - I have not modified these settings.
Please mirror these settings and test again.
There is an m.root-servers.net missing with an unknown entry - please add this too.

Have a read through this:
http://www.computerperformance.co.uk/w2k3/services/DNS_root_hints.htm
Essentially they are places to go to look up DNS info outside your domain - so at present you are looking internally, then checking for your root hints, which directs you back to your own server - going round in circles basically.
Remove your existing root hint, add the ones I have shown - and then click on the Monitoring Tab and check both simple and recursive tests and click on Test Now.  If you get a PASS in both Simple and Recursive - you are good to go.

This article is relating to Windows 2000 but is also relevant for Windows 2003 - it explains why the root hints are needed.
http://support.microsoft.com/kb/235689
To answer your question about cache.dns - Yes - as long as the root hints are similar to the screen shot I attached.
Remove your root hint and add a couple of root hints for tests and you should see the DNS errors in the event logs stop.
