BT Wireless Networking and Internet Sharing... HELP!

[mnx]

Ok... Here goes...

I have a little home network running (wired) 2 PCs, 1 Twinhead notebook and, now, a Powerbook 667 all connected with CAT5 cabling to a D-Link 704P router. I also have a couple of USB BT dongles to work with a Sony Ericsson Z600 and a Palm Tungsten W with Palm BT Card.

All is fine and good except for one little thing: I can't seem to connect to the network via BT from the Pbook. I don't exactly know how to do this so I'm begging for help here.

On my XP notebook, I just plug in the dongle and a network connection pops up in my network configuration window. The notebook automatically hooks up to one of the desktops running ICS to its own dongle. In other words, I remove the lan cable, plug in the dongle and continue browsing the net.

On the Powerbook, I plug in the dongle... open up safari... then... nothing... "Cannot find host".

I opened up system preferences --> bluetooth and confirm that my desktop is in the list of devices... network access is stated as an available service from the desktop

I then went to system preferences --> network --> bluetooth... i'm faced with a window saying Configure IPv4 [via PPP] (other options are Manual and via AOL dialup)... now I'm lost... help please...
