SBS 2003 shows two gateways on external nic

Installed new SBS 2003 over the weekend, Internet was working flawlessly all weekend.  Joined computers to the domain, etc. but no users on the system until this morning.
The Internet connection drops, run the Internet connection wizard and we're back up, no errors in event log, not an ISP issue. So far it has done this twice.  In looking at external network card configuration, status, details it shows the correct gateway and then an incorrect gateway with one number wrong. I had entered this incorrectly the first time I ran the wizard so re-ran the wizard with the correct gateway and everything worked until this morning. I don't know if that is what's causing this disconnection or not but it's the only thing I can see. Is there a way to get rid of this?

Start -> Settings -> Network Connections -> Right click the external network -> properties-> check the properties of TCP/IP -> Advanced
How many Gateways you have under IP Settings tab? Can you get rid of the wrong one?

How silly, never considering looking there thought it would be some registry change!  In fact it shows 3 there, including the previous server's internal ip which is from before this new server was setup I had configured it's gateway manually to the old server so I could get it on the Internet.
I will remove both the incorrect ones, hopefully that will fix it.

That didn't really fix it even though I re-ran the ICEW.  It wouldn't make a connection at all, ping anything external returned a hardware error. I don't know whether this was actually a hardware problem or not, I suspect still a configuration problem though everything looked right.  I have 3 nic's in this server so I disabled the problematic one and configured the 3rd one as the external. So far, we've been up for about 45 minutes. I'll wait a while and see whether there are any more issues. Thanks.
Hi. Just want to find out how many network cards are you using? I faced this problem too when i have one NIC for WAN and the other for LAN. Your gateway should be pointing to your router or internet modem.  In Command Prompt, run  "Route print". Check what is your default gateway. It should be the one pointing to your internet router/modem.

I'm using 2 cards. It's all working fine now, the gateway is pointing to our T1 gateway.
