My pc has suddenly stopped sharing on SMB sharing to my Xbox (XBMC). I can see the pc name on my WORKGROUP but it sees no further than this, even though I have six shared hdd's. I have tried this with 2 different Xboxes and the problem occurs on both of them. I can see the entire contents of my daughter's laptop, so it is not the Xbox or XBMC that is at fault. I have tried running an XP repair on the pc but to no avail. I think it may be a service that is failing but I turned all networking services on last night and the problem still occurs. Any ideas?
