Hardware

I updated a friend's Mac A1342 from Lion v10.6.8 to El Capitan then to Sierra v10.12.3. You can't update 10.6.8 to Sierra direct as minimum requirement is version 10.7.

Mac was a bit slow after the update as photoanalysisd and other daemons are running in the background. I also decided to upgrade the RAM from 2 x 1GB to 2 x 2GB, so I shut it down, when I switched it back on that is the time the progress/loading bar is stuck to 100%.

The reason why it had been disconnecting every 4 or 5 minutes is because two different modems from two different locations were trying to authenticate at the same time, even though both modems are set to dynamic and there were no broadband username and password set to the modem.

When setting up new POP account on Outlook 2016, testing it makes sending and receiving shows the error 0x80004005.
Computer is joined to a local domain, and email being setup is a POP account provided by a different mail hosting server.



Solution: On HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297eb,

create or set a new registry DWORD value, named ProtectionPolicy, set the value 1

Disabling notification (receiving email) didn't work.

Windows 10 Home would not map or access network shared drive or running Netlogon script. It comes up an error 0x80004005.

Solution: Add a Windows Credential of that network you were trying to access.
