Solved Cannot start PNRPSvc - Error 5: Access denied

[geob]

An attempt to upgrade Win7H&P-64 to Windows 10 resulted in Win 7 being restored. Restored a system image, ran sfc /scannow & chkdsk /f to end up with:

The Peer Name Resolution Protocol cloud did not start because the creation of the default identity failed with error code: 0x80070005.

​

I have tried all the fixes mentioned at Can't start Peer Name Resolution Protocol. Nothing has worked:

deleting C:\Windows\ServiceProfiles\...\idstore.sst
Leave HomeGroup => couldn't be done
deleting entries in C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys
resetting password of Local Service
grant Local Service full control of C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys

​

I could again restore the system image but strongly suspect this will only delay the inevitable need to solve this issue. Please advise.

Thanks.

Logged in with an admin account?

Maybe:

net localgroup Administrators /add networkservice
net localgroup Administrators /add localservice

I was, yes. System is wife's office computer. I'll try adding services to Administrators group next time she lets me at it. For now I've restored the system image.

Maybe:

net localgroup Administrators /add networkservice
net localgroup Administrators /add localservice

No joy here, either. Best guess - drive is in need of replacement.

Ok, tried registry permission reset yet? (Official version of post #30 in the link you gave)

@GokAy I may have been too hasty with respect to adding to the Administrators group. After a reboot the service was indeed started.

Turns out there were also some significant permissions issues, but not that affected the service.

Thanks for your assistance.
