On my home network I am running Win XP on a desktop and Leopard on my MBP...I see both my Windows computer in finder and my MacBook Pro from my Windows network..Recently when copying file(s) from a sharing folder on windows to my MBP desktop, I get the message, that I don't have permissions to read/or write or something like that and it wont any longer copy..I don't know where the prob is, my MBP or Desktop (Windows)..Any ideas..??
