linking remote windows domains

Hi,

So i have two windows domains, one on the west coast (win 2k) one on the east (win 2k3 sbs). I would like to be able to share folders and/or drives between the two.

I thought i could do this with vpn, but when i vpn into the sbs server (from the w2k domain), i cannot access anything on the network, but i can ping anything (even things that dont exist).

I think the way to go about this is to create trusted network, but i dont know much about that.

any advice would be much appreciated.

Thanks.
