Thanks, I think that was what I was looking for. I wasn't certain whether Exchange
could ONLY query GCs or if they could get info from DCs as well. In any case, I'm
thinking that there should be 2 GCs even in a small single-domain environment, just
for redundancy's sake. Otherwise the GC represents a single point of failure.
