"Peer Name Resolution Protocol" will not start?

    Question

  • Everything was working fine (using RTM) for about a week... I find today that my Homegroup was not working. Further investigation finds that "Peer Name Resolution Protocol" will not start, seemingly causing the problem. It gives some error that no Bing or Google search find ANYTHING for. Even MS support gives nothing. Nice going MS superstars... lotta good an error code that cannot be looked up is!

    Does anyone have a fix for this?

  • Hi,

     

    Does the issue persist after doing a clean installation of Windows 7?

     

    If the issue persists, I suggest we perform the suggestions from the link below:

  • I tried a repair/upgrade... did not fix the problem. I had to install clean. I had nothing installed on Win7 except MS Security Essentials. I was using it as a media center.

    here's the error in case someone at MS decides to do the right thing and fix this...

  • From an elevated CMD prompt.
    Net stop p2pimsvc /y

    Then delete the following file.

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

    reboot and you should be able to rejoin the homegroup.

  • Wish I would have had this info 11 days before you posted it... Win7 is still very buggy. :(

    Brian, maybe you can put that in a KB so people can find the info when needed?

  • 1) Start Menu, Programs, Accessories, right click on Command Prompt and select run as Administrator

    2) Start Menu, Programs, Accessories, Windows Explorer, Copy and Paste this C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking\ into the task bar at the top and you will see the file. Highlight it and press delete.

     

    Google of course could easily sort this out for you too!

  • locate the path manually, by opening Windows Explorer and expanding the folders, the AppData folder is a 'hidden folder' you will need to view all hidden folders\files and 'system protected files' so you can see the folder, then you will see the file.

  • This did not work for me for some reason. I am having problems initializing the Peer Name Resolution Protocol, and I believe that to be the issue. Any further suggestions?

    Thanks.
