SBS 2003 machine has only one NIC. Its Windows firewall cannot protect the LAN, by design.
So now it's off (by SBS install).
My question is,
can Windows firewall, if started, protect the SBS host machine itself? (the host only, not the entire LAN)
If so, is it safe to start it directly (Configure Firewall under Internet and E-mail), of should I run again the internet wizard.
