Error 10050 : A Socket opreation encountered a dead network , evo za homegroup The homegroup is not available because you're not connect to the home network a jos smijesnije kada u services.msc pokusavam da mu pokrenem naravno izbacuje nove errore Windows could not start the Homegroup Listener service on local computer , Error 1068: The dependecy service or group failed to start sad sam za ovaj zadnji error nasao yahoo tzv. rijesenje ali opet ne radi , bio bih jako zahvalan kad bi neko mogao pomoci  

If you are not able to join Homegroup on your computer, I suggest that you follow the below step to fix this issue:
a. Click on Start and type ‘cmd’ in the search field.
b. Right click and Run as Administrator. At the command prompt type:
Net stop p2pimsvc /y
c. Go to the location:
"C:WindowsServiceProfilesLocalServiceAppDataRoamingPeerNetworkingidstore.sst"
d. Right click and rename to file to .old
e. Reboot the computer and Join Homegroup.
