Hi, You can open HomeGroup troubleshooter to troubleshoot the issue first: http://windows.microsoft.com/en-US/windows7/Open-the-HomeGroup-troubleshooter Furthermore, you can temporally disable the firewall and antivirus program for test. If the issue persists, also please try to delete the old homegroup, and create a new one to see if the same issue occurs. Regards, Leo Huang Leo Huang TechNet Community Support
