Can I have more than one default gateway on a router?

Hi - I have a Windows 2000 box with three network cards:
1 - Private LAN
2 - Cable modem (for internet access)
3 - ISDN modem (for web hosting)
I set up the machine to have 2 default gateways so local traffic for the Internet goes through the cable modem (since it is the first default) and traffic inbound for a domain name comes in on the ISDN line and goes out through the ISDN line. I was surprised that it works this way, but it works great!

Problem: Sometimes the main default for the system switches unexpectadly to the ISDN modem instead of the cable...

modem (as it was setup).

Any ideas on how can I stop it from switching?

You should only have one default gateway on the router. If the ISDN interface connects to a private network, make a static routing table entry for that network.
