When you're unable to create a new homegroup or join an existing one, it usually means that either the required services are not running or idstore.sst turned corrupt.

[Solution 1] Turn on network detection


  1. Open the Control Panel.
  2. Open Network and Sharing Centre and click Change advanced sharing settings.
  3. Extend Private and select Turn on network discovery.
  4. Restart the computer.

[Solution 2] Turn on the required services


  1. Open Run and execute Services.msc.
  2. Right-click on the required services, click Properties and change the Startup type to Automatic.
  3. Click Start in the left pane if the selected service isn't running yet.

    • COM+ Event System
    • Computer Browser
    • DHCP Client
    • DNS Client
    • Network Connections
    • Network Location Awareness
    • Remote Procedure Call (RPC)
    • Server
    • TCP/IP Netbios helper
    • WLAN AutoConfig
    • Workstation

  4. Repeat these steps for every computer you wish to include in the homegroup.

[Solution 3] Reset the idstore.sset file
