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?

Joe Bush, You're the man!! Thanks for posting your solution. It solved my problem.

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
