I upgraded my 8.04 PC to 8.1 (RC) without any problem (it seemed), and installed 8.1 (RC/dual boot) on my games (WindowsXP).

Prior to this the two machines shared files without any problem, but now the WindowsXP (dual boot) and the 8.1 (stand alone) PCs can't see each others shared folders (although each can ping the other successfully).

On the other hand, the 8.1 (dual boot) PC can see and read/write from/to the shared folders on the 8.1 (stand alone) PC, although the latter cannot see the shared folders on the former.

Sharing isn't mission critical as I can transfer using an external pocket drive, but its kinda thrown me and I would prefer to fix it.

Where do I start?
