I've happily shared folders from my Mac Mini to a Windows 7 PC for years. My Win7 Laptop can still see the shared folders on the Mac.
This week, I upgraded my desktop to Windows 8. Now I can see the Mac itself in the Network but there are no folders in it. My Linux-based NAS and other Windows PCs haven't been affected at all.
What do I need to do to get my network back to it's old state?
