PNRPsvc Failed To Start, HomeGroup and Peer Name Resolution service Problems

We recently con­fig­ured a cus­tom sys­tem for a client using Win­dows 7 Home Pre­mium. Every­thing was run­ning great until recently when our client said they were receiv­ing blue screen errors, and hav­ing net­work prob­lems. A quick review of the error logs showed that the prob­lems were all stem­ming from Peer Net­work­ing Ser­vice, PNRPsvc, and other depen­dent ser­vices and there fail­ure to start. After research­ing the issue we found that the prob­lem relates to a file named “idstore.sst”. This file is encrypted, and con­tains infor­ma­tion relat­ing to your Home­group, and Home­group set­tings. In our case, we believe an out dated ver­sion of Syman­tec cor­rupted the file while con­fig­u­ra­tions were being made.

So our solu­tion is as fol­lows. First we updated our anti-virus client, as well as con­fig­ured all related secu­rity ser­vices. We then deleted the fol­low­ing file…

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

You may need to show your hid­den files and fold­ers in order to nav­i­gate to this loca­tion. Once that was done we restarted the com­puter and again tried to con­fig­ure the Home­group. At this point our issue was resolved. We’re able to make changes in the Home­group con­fig­u­ra­tion, and our error log is clean, clear, and free of errors.
