There is no limit to the number of GC's per AD site or per subnet, where did
you hear that it was only possible to have one?

Like you said, having to many on the other hand could cause a lot of GC
replication.

Hi All

One question if I may just butt in just a second please. Only one GC per
site? I have been running two on our single site of about 50 machines for
several months without error. If I had a user location with say 180 users
and a total of 225 machines and all on one IP subnet I would certainly want
more than one GC? Are we talking AD Sites or IP Subnets as sites? I assume
the former in which case I have another question. Whilst creating Sites is
recommended it is not compulsory and whilst AD may not work as well without
them it isn't a prerequisite as I understand so what is the problem with
multiple GC's' per Site?

I do appreciate that too many GC's overall can be just as bad as to few.but
one per Site seems low to me?

Many thanks in advance.

Regards,

Paul Lemoidis.
