When the computer resolves "taz2" what IP is it using? Hopefully your localhost is the same IP.
** Oops what am I thinking, taz2 should be your LAN IP, while loaclhost your loopback 127.0.0.1
Also when you try to connect to taz2 from another computer, is this computer on the LAN with you, or is it a remote PC? LAN to LAN connections shouldn't work unless you're passing LAN IPs.
