Leopard not seeing other comps on network

Am I retarded or what?

How the hell do you get two macs to see each other on the same network?

PMG5 is 10.5 MacBook is 10.4.10.

Enlighten me please. 10.4 was never a problem apart from when it didnt want to work, however Leopard is either a) not working b) confusing or c) both.

Please help I need to know pretty much right now.


Both on same airport network. Both can access net etc. Neither can see each other as far as i know.

 

Ok so now the MacBook 10.4 appears in Leopard (must need to index it first?). It says 'connecting' but does nothing. The spinning loady thing in the bottom right spins for a bit then disappears.

I'm having one hell of a ****** day. Lost 300GB of iTunes stuff cause Lacie are ****. My mobile died today too.

Help me Pbpbpbpbpbpbpbleeeease!
