You want to try with the domain administrator account, not the local 
administrator.
If you're logging on as administrator, and log on to is set to the 
domain, then you are already doing so and something most unusual is 
occuring - suggestive of an admin removing administrator access to the 
root filesystem, or to certain parts of it.

Spinning complacently in the darkness, covered and blinded by a blanket
of little lives, false security has lulled the madness of this world
into a slumber. Wake up! An eye is upon you, staring straight down and
keenly through, seeing all that you are and everything that you will
never be. Yes, an eye is upon you, an eye ready to blink. So face
forward, with arms wide open and mind reeling. Your future has
arrived... Are you ready to go?
