    Since upgrading My DC to Server 2012 R2, my Windows XP PCs can’t connect to the domain.

    Your XP PCs can’t connect to the Server 2012 R2 domain because Server 2012 R2 uses SMB 2 and above, whilst Windows XP only supports SMB 1.

    To fix this, on the Server 2012 R2 domain controllers, install the SMB 1.0 Feature and make the following registry change:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\DependOnService

    Change SamSS Srv2 to SamSS Srv

    Then restart the Server (Lanmanserver) service.

    Windows XP PCs will then be able to connect to the Server 2012 R2 domain.
