You can:

A) Connect your cable modem to your server machine, then have a crossover cable running from your server machine to your work machine. Then just use Windows ICS (The server machine MUST be on in order for the work machine to have access to the internet).

B) If your cable modem has DHCP/Firewall built in, you can simply buy a switch and connect it to the modem, and the modem will give out internal IPs to anyone connected to the switch.

C) Buy a router.
