How can I get a Windows 2000 server to properly configure its clients to see specific gateway?

Question

I have a Windows 2000 server connected to a hub. I also have about 20 Windows XP machines (clients) connected to this hub as well. I also have a Netgear firewall, which is connected to both a cable modem and the hub.

The Win 2000 server has IP 10.100.100.1, and the Netgear firewall has IP 10.100.100.141.

Right now, what I'm doing is going to each client and configuring the Default Gateway entry manually. What I'd LIKE to do is have the client's IP settings set to "Obtain IP Addresses Automatically" and have the Netgear's IP address come up automatically.

I'm assuming this can be done on the Windows 2000 server, as it's the DHCP server on the network, but I have no idea how to do it.

Could someone give me a step-by-step on how to do it?

Also, is this the best way to get my network to have internet access? Right now, each client loses internet access about every 10 mins, which a "repair" will fix, but it happens so regularly that it's getting to be disruptive. Tnx for hlp!

Pretty simple. Open your DHCP from administrative tools. Go to scope options. The default gateway is going to be option 003 (router). Add your router's IP here. Poof! you're done! It will push out the router's IP as the default gateway to all DHCP clients.
While you're at it, you might consider adding DNS servers as well (option 006, I think... it will walk you through it). This could go a long way towards fixing your "internet down" issues.
