HomeGroup: error 0x80630203 / Leaving/joining the homegroup is not possible
Hello, I have the following problems with the HomeGroup: I choose View or print the homegroup password: The password window does not pop up. Without the password no other computer can join the homegroup. I choose Change password: On your computer it is not possible to create a homegroup. I choose Leave the homegroup: Your computer could not leave the homegroup. I checked the following services: HomeGroup Provider: started HomeGroup Listener: started Peer Name Resolution Protocol: not started; error 0x80630203 Peer Networking Grouping service: not started; error 1068. Peer Networking Identity Manager service: started PNRP Machine Name Publication Service: not started; error 1068. Who can give advice?

Hi, To leave HomeGroup completely, please perform the following steps. a. Click the Start Button, type "cmd" (without quotation marks), in the search result list, right click on Cmd.exe and select Run as administrator. Note: If you are prompted for an administrator password or confirmation, type your password, or click Continue. b. In the popup window, type the following commands and press Enter one by one: Net stop p2pimsvc 2. Access t he following folder and clear all files inside: C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking 3. Click the Start Button, type "cmd" (without quotation marks), in the search result list, right click on Cmd.exe and select Run as administrator. Net start p2pimsvc If the issue persists, I suggest you upgrade the virus definition and run a complete scanning for a test.

Clear all files inside C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking did not help at all. After searching for a long time, the following turned out to fix the problem: C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys ----> Took over possession: Admin (my user account), security everyone added full possession Cleared all files inside MachineKeys, restarted Then left the homegroup: Result: There is no homegroup available in the network Now Network and Sharing Center shows again: - access type: Internet - homegroup: ready to create - connections: wireless network connection C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys ----> security everyone deleted full possession

Thanks Joe Bush; I did the same thing but I didn't delete the MachineKeys file. Instaed I renamed MachineKeys_old and created a new file in the same folder called MachineKeys and gave full permission to Everyone and System. The 2 x Peer Name Resolution services started after I did this. After I rebooted I Joined the Homegroup succesfully. I am running AVG Internet Security 2010. I have the Homegroup entry in the active firewall profile set "Allow from all" and the same for all IPv6 services and protocols. Rename: C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys To: C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys_old Create a new: C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys and set permissions Everyone Full controlThe VipX
