Paul is right; always have at least two GCs, two
GCs per site if you can.
And there is nothing wrong with single domains
or even small forests having ALL DCs be GCs.
The reason that all DCs are not GCs to start is
that in large (or even Giant) forests the DCs would
all have to hold a reference to every object in the
entire forest which could be quite large and quite
a replication burden.
For a few hundred, or a few thousand users even,
this not likely to matter unless you have really
poor WAN lines.
Single domain, all GCs.
Small multi-domain forest, probably all GCs.
