Hi Adrian,

In some installations I've seen evidence that AD itself can be configured
to do "load balancing" of the kind you describe.  In such installations, if
you access the domain controller through DNS, e.g. "thedomain.com", you
reach one of a number of different machines, automatically.

The exact place I've seen this is in the context of a large network that
was being crawled using JCIFS, which had multiple domain-based DFS roots.
Resolving each such root required a back-and-forth with a domain
controller, of which we eventually realized there were more than one.  (And
at least one of them was out of synch, which caused us no end of trouble.)

MCF doesn't try to recreate that kind of load balancing, since it would
appear to be a duplication of effort, but it's possible that our current AD
authority doesn't play well in such an environment.  If that's the case, we
should fix it, rather than create our own idea of a load balancer.

Thanks,
Karl
