I have some troubles with homegroup's feature using two windows 7 64-bit based devices (laptop and desktop).
Desktop is connected via LAN cable and the laptop via WiFi. Both use the same subnet and working group (by default - WORKGROUP). I am able to ping the laptop from the desktop and vice versa.
On the desktop I created a homegroup, and have successfully connected the laptop to it. I can view all shared folder on remote machine, but for some reason I can't access them.
When I share a folder on the laptop or desktop (using the sharing wizard) I can't access it from another computer in the homegroup (I think it is due to NTFS permissions). When I double-click on shared folder I get an "access denied" message.
I tried to add an NTFS permission to the folder for "All users" (read, listen, execute), and then I can access it - but this is not solution of problem.
I think that windows can't identify connecting device from homegroup as a member of "HomeUsers" group. But why it can't - I don't understand.
