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.
