SBS 2003 Single NIC Setup questions

I would like to check my IP config / DNS Settings on my server and one of my workstations.
Again, my setup is: Server Single NIC - to switch, - to Netgear Router with firewall enabled - to DSL Modem.  Netgear has DHCP DISABLED, a static IP set up and my ISP's DNS server setup.

The reason why I am asking is because I see this WARNING LOG in my DNS Log:
The DNS server encountered a packet addressed to itself on IP address 192.168.1.6. The packet is for the DNS name "lb._dns-sd._udp.0.129.37.10.in-addr.arpa.". The packet will be discarded. This condition usually indicates a configuration error.
 
What have I missed here?

The ipconfig results:

Nothing wrong with your ipconfigs.  However, there may be something wrong with your DNS server settings.  MS KB article here:  http://support.microsoft.com/kb/218814

Check your root hints in your DNS console.  (Start > Admin Tools > DNS, then right-click on the server and select Properties, then select the Root Hints tab.)  Your own server should not show up in the root hints list (if it's there, remove it), but there should be thirteen servers listed there with names like a.root-servers.net, b.root-servers.net, etc.  If the list appears incorrect, the easiest way to fix it is to click the "Copy from server" button and enter the IP address of one of your ISP's DNS servers.  This should populate the list fully.  If it only populates names and not address, as sometimes happens, close the DNS console and simply wait a few minutes, then re-open the console and check again.  Sometimes it just takes a little while to resolve all of the addresses.

That was it.  Does this reveal any additional setup errors that I may have made?

No, you're probably good to go.  This is a fairly common thing to see, but it doesn't imply that anything else is messed up.
