    I have 3 computers on my network running Windows 7.

    I created a homegroup on one, and successfully connected to it from another.

    On the third computer, however, I'm having some problems. If I try to join the homegroup the normal way, I get the message "Windows cannot set up a homegroup on this computer".

    I checked into it, and found out the "Peer Name Resolution Protocol" service needs to be started for the homegroup to work properly. When I try to start it, I get this error:

    (Error 0x80630203)

    This computer is running 7 Ultimate x86, upgraded from Vista Home Premium x86.
    The computer that created the homegroup is running 7 Ultimate x64 upgraded from Vista Ultimate x64
    The other computer that connected to the homegroup successfuly is running a fresh install of Windows 7

    See this thread,,, do everything in it to see if it resolves the issue. Ignore that it is for XP.
    The problem is probably related.

    Basic Samples

    Reason,,, 0x80630203 = PEER_E_DATABASE_ACCESSDENIED = The requested access to the database has been denied.

    Thank you so much. Here's what I did to fix it:

    1) Went to C:\Users\All Users\Microsoft\Crypto\RSA

    Set Group "Everyone"'s permissions on the folder MachineKeys to Full Control
    Set my current user's permission on the UserSID folder to Full Control

    service started perfectly!
