Electrical Gremlin

Hi I need some help.

Got a 2007 freelander 2 that had no issues to speak of until this morning. Got to work (45 mile each way) and the 4 doors wouldn't unlock or lock with either the key fob or the buttons on the dash, I did unlock it before leaving with the fob though. Also none of the windows will go up or down and neither do the electric mirrors work now....
The boot however will lock and unlock on both the fob and the dash buttons?
With all the doors and the boot shut if I press the lock button on the key fob it sounds the horn as if a doors open, but it ain't.
I have disconnected the battery for a good hour and reconnected, no difference, and I've checked every fuse bit none have blown, if anyone has an idea what else I can try it would be much appreciated.

How old is the battery do you have a second earth fitted f2 very power hungry if your battery is over 4yrs old its on borrowed time

At a guess, a door status sensor isn't telling the CJB that the door in question is closed.
Best get a diagnostic done, and see what comes up.
