I have a desktop running Win7 64 bit Professional, and a laptop with Win 7 32bit Ultimate. They are hooked up to a router (laptop wirelessly, desktop by LAN cable). Problem is, when I share folders on either, the other says "You do not have permission to access". I have modified the share settings to "Everyone, Full control". I do not use a Homegroup (nor does it work - I tried).\ I have identical user accounts on both; same username, same password. Firewall is NOT stopping traffic, since I can use Synctoy with no difficulty, and I can access the Laptop's DVD ROM for some reason!! Please help. This is SO annoying. I can't believe Microsoft managed to f up such a simple thing!
