I have a laptop and a desktop which were both participaing in a Homegroup.  It stopped working, so I tried to "leave the Homegroup" from both machines, intending to recreate it.  By the way, standard networking and file sharing is still working.  The desktop allowed me to leave the Homegroup, but I receive the "Windows couldn't remove your computer from the homegroup" message on the laptop.  I have run the network and homegroup troubleshooters numerous times on both machines.  I have also researched and tried everything I could find on the web, with no sucess.  Please tell me how I can reset the Homegroup settings on my laptop.

Here is a solution that might work.  It worked for me. 

"Researched the problem and found the solution. A file was corrupted and deleting it got the PNRP service running. The file was recreated correctly when the PNRP service started up. Here's the file for future reference:

C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking\idstore.sst"

    Unfortunately NONE of these have worked for me - tried just about everything including a system restore which failed so now I'm stumped.  Any other ideas?

    Before doing the below kindly do this Go to "C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking\idstore.sst" and delete idstore.sst Now follow the below steps. 1. Press the Windows key or the "Start" key. 2. In the "search program and files" type services or services.msc 3. You will see a new window opened. Now out here scroll for the following services names:- 3.1 Peer Name Resolution Protocol 3.2 Peer Networking Grouping 3.3 Peer Networking Identity Manager 3.4 PNRP Machine Name Publication Service 4. You have to start each of them. Now you cannot start them unless you enable them. You need to enable each of them. 4.1 To enable right click on the service and go to properties. You'll find it disabled there so just click on the drop down menu and make it automatic. Once you have done this for all the services mentioned, simply start them. 5. Restart your PC and bravo you are done :). After doing the above mentioned you shall be able to Leave a homegroup or Change the password, etc. Any problem in the above let me know will be glad to help ya :)

    This did it for me.  I was able to leave the home group.  THANK YOU.

    It wasn't just the idstore.sst file for me that fixed it.

    I had to delete ALL contents under: C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking\

    and then reboot.

    Same issues as stated above...

    Deleting idstore.sst alone did not fix it...

    Disabling Home Group Listener and Home Group Provider alone did not fix it...

    Doing both, worked like a charm, left the home group, and created a new one.

    Thanks
