I have this small problem. I have re-installed windows home premium SP1 on my sister computer to upgrade to 64bit from 32 bit home premium SP1.
After finishing the install and installing most of the windows updates I then proceeded to set the computer to join my home-group network. But this just keeps failing saying unable to create home-group. I am not trying to create a home-group as my other 2 computers (desktop & laptop) are already part of the home-group using the same shared pass-phrase, I am just trying to join the Home-group already present, so I do not understand the message about creating a home group as I clicked on the join selection.
Have tried to find solution using MS fixit and trouble shoot which say to check firewall on the desktop which is originator of the home-group which I have done and can find no problems (which there should not be as the laptop would not be able to connect to the home-group either if there was, and I have no problems with either the desktop or Laptop connecting. I have checked that the advanced sharing options are set same on all computers with password sharing disabled.
Also when she was on 32 bit win7 there was no problem with joining home-group.
I wonder why on a completely clean install of windows 7HP 64 bit I now cannot join the home-group. The other computers are seen on the network map on all machines and I can map a drive no problems to the desktop from my sisters computer (which is also a desktop). so it seems I have no network problem as such.
Anyone have any idea what it is I may be missing that prevents the joining of the home-group? (Pass-phrase used is copied and pasted from my desktop to ensure correct input)
