After upgrading my Windows 7 Ultimate desktop machine to Windows 8 Pro, this machine has created a new HomeGroup.
I now want to connect my Windows 7 Home Premium netbook to this new HomeGroup.
On the W7HP netbook, the HomeGroup created by the W8P machine is shown as the detected HomeGroup.
When I click "Join", and enter the password for this HomeGroup, taken from the W8P machine, the W7HP machine tries to connect, then reports "Windows cannot set up a homegroup on this computer".
All the HomeGroup trouble-shooter on the W7HP machine can suggest is that all computers in the homegroup have to have synchronized time. I've done that -- each machine is synchronizing via time.microsoft.com, and I've forced them to synchronize.
Running the trouble-shooter on the W8P machine reveals no problems.
Telling the W8P machine to leave the HomeGroup, and creating one on the W7HP machines doesn't work either.
What do I try now?
