Once the machines are all up and running and you think everything should be working, unplug the power to the AsanteTalk, wait a minute, then and re apply the power to it.

This should force the AsanteTalk box to renegotiate the zones. Unless you have a bridge or other device managing the AppleTalk network, all configuration should be blank.

I personally have a Win2k server box providing three Zones, when I repower up the AsanteBox the Mac leaps into life saying that the "Network is now available".
