Is ed.ac.uk your Active Directory root as well? If so, my experience is 
that pointing it at anything but domain controllers will eventually lead 
you to issues.

It's not to say that this totally forbidden, but there is (was?) 
Microsoft best practices documents suggesting avoiding this 
configuration entirely when possible, although there were ways to 
mitigate most of the negative side effects.

Obviously if you can run a split DNS environment this is less of a factor.
