DNS Requests

On my router logs I can see my Windows 2000 SBS machine keeps querying the following addresses on port 53 (DNS), I have no idea where this is coming from as I have different primary and secondary dns configured on the SBS and the same ones on the router. A few of the addresses its querying are
202.12.27.33
192.33.4.12
198.41.0.4
128.8.10.90
192.33.4.12

My system is fully virus scanned.

Hi Sid_F,
those addresses are actually DNS servers, they are some of the root DNS servers: your machine is probably configured to use root hints (look into DNS properties).

You see the server quering Internet root DNS servers for resolving host/domain names not local to your domain.
Open your DNS admin, right click on your server, select properties and go to the tab named "Root Hints", here you'll see the list of root servers.

Great. Should I disable this as really what I want is the sbs server to only handle local DNS queries and for my router to handle all queries for the internet.
