Windows 7 Homegroup - Peer Networking Grouping Service failing to start

I had a weird Windows 7 Homegroup issue happen lately. I had used Homegroup previously with success and knew both computers in the Homegroup were successfully connected. However recently one computer would not connect. I tried changing passwords, made sure ports were open through Windows firewall, and made sure the computers had other forms of communication open. Everything looked fine, but still no Homegroup.
I then ran the Homegroup troubleshooter and it was telling me that the Peer Networking Grouping Service could not be started. I fired up the Windows Services console (Start > Control Panel > Administrative Tools > Services) and found that indeed the Peer Networking Grouping Service was stopped. I right-clicked and selected Start. It failed with an error 1068 saying the dependency service was not able to start. I then tried to start the Peer Name Resolution Protocol service which also failed with an error 0x80630801: 0x80630801. After quickly searching around I found that the problem resides with a corrupt file in the PeerNetworking folder on the system drive.
UPDATE: To see the below file and containing folder you will need to show hidden folders in Windows Explorer. To do this open Windows Explorer and click on Organize > Folder and search options. Then on the View tab, under the Advanced settings section select Show hidden files, folders, or drives. Click OK.
I browsed to
and deleted the idstore.sst file. I then went back to the services console, right-clicked Peer Networking Grouping and selected Start. This and the Peer Name Resolution Protocol services immediately started back up. I then had to run the Homegroup troubleshooter one more time to refresh the Homegroup information. Everything works great now.Code:C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking\
Hopefully this will help someone with this same problem
