Good Firewall for Win2K?

[Krusty*da*Klown]

I have Win2K pro and am on Cable and just wondered what is a good Firewall anyone is using.

Also I turned disabled Netbios over TCP/IP (under the Wins tab for Advanced Props) and File sharing for my NIC connected to the Cable modem. Does this help at all?

I'm using Zonealarm as our firewall with W2k and it's been doing great.Had my ports probed and was in stealth mode with it on.
And the best part is it's free.
