You cannot access DPAPI data after an administrator resets your password on a Windows Server 2012-based domain controller

Symptoms
Assume that a domain controller is upgraded from an earlier version of Windows Server to Windows Server 2012. After an administrator resets a user's password in the domain, the user cannot access Windows Data Protection API (DPAPI) protected data. For example, the user cannot access the certificate private key.

Note This issue may occur when users change their password by themselves.
Cause
This issue occurs because of an incompatibility in the authentication mechanism that is used by domain controllers. If DPAPI keys are backed up on domain controllers that are running on pre-Windows Server 2003-based servers, and the same keys are retrieved from domain controllers after an upgrade to Windows Server 2012, key retrieval fails after an administrator changes a user's password.
Resolution
Important Do not install a language pack after you install this hotfix. If you do install a language pack, the language-specific changes in the hotfix will not be applied, and you will have to reinstall the hotfix. For more information, see Add language packs to Windows.

To resolve this issue, apply the hotfix that is described in this article on the Windows Server 2012-based domain controller. Even though this issue was observed only on Windows Server 2012, the hotfix also applies to Windows 8 and Windows RT.
