Drive Sharing Problems!

I've got several macs on the home network, and one of them is on
jaguar, the rest on leopard. I'm having no luck seeing the jaguar
drives from any other machine. The leopard machines all talk fine.
I've got two firewire drives on the jaguar machine, all with all
permissions read and write, and have applied those permissions to all
enclosed folders. From a leopard machine, I can only see the top HD
node, but only the drop box in the single user directory. I've turned
on everything to share except the firewall. I've tried it with ignore
permissions on and off. no luck. I want to be able to mount all three
drives on the jaguar machine on all the leopard desktops.

Any ideas?

Thx!
