Installed win8 and now trying to connect to my Windows 7 machine. Windows 7 status is: connection internet, joined, local area connection. Win8 status is internet, not joined, local area connection. So I set up a homegroup on Win 8, have a password etc. Went to Windows 7 and tried to "reset" the home group connection there. Got error messages, " Cannot leave home group and Cannot remove your computer from Home Group" The win 8 error message initially (trying to connect to Windows 7) was "type in the user name and password??" Have no idea what that might be, assuming that is for the Windows 7 home group initial setup long ago. Hence trying to reset it. Other error messages (Windows 7) during this whole process is " Peer network resolution protocal service PNRP or peer network .. service is not (P2pimsvc) running. Also, Peer networking Grouping service is not running". I have most of the settings to ON, network discovery, sharing etc. This kinda stuff reminds me back in the days trying to get a HDD recognized by # cylinders, sectors etc. Right now trying to do a discovery just times out after 3 minutes or so, even thought the windows says may take as much as 90 seconds.
If it matters, all machines connect to internet no problems, and the two machines are connected via a network switch
