I have two offices here in the states that currently
reside in the same domain with DC's at both sites. We
are opening a third office in the UK but will most likely
have a fairly slow connection coming back. My question
is related to whether or not the box I send over there
(mainly to do logon's, print queue's, and house their
Exchange mailboxes) will need to be a DC or whether I can
get by just making it a GC. I'd rather not have it be a
DC just to cut down on any unnecessary traffic but want
to be sure that will be sufficient.
First thing - You can't have a GC without DC.
You have two (ok, more but let's discuss about this two) choices, I
assume thath You will be an administrator of both locations in the
states and in the UK, so ... :
1. send them box configured as another DC in Your domain and configure
proper sites and subnets
2. send them box configured as additional child domain in Your tree
ad.1
Remember thath if you configure this box as additional DC in Your
existing domain this DC will have to replicate whole domain data with
DCs in the states - You can set replication schedule to keep this traffi
out of working hours but You have to take it under consideration.
ad.2
In this case You don't have to replicate domain data across slow WAN
link (I don't know how slow this link will be) Between these locations
onlu forest wide data will be replicated. Users will have their own
domain resources and You should place at least two DCs for this domain
in the UK location
The replication is only one of the factors which can affect your design
- for example Exchange - You can place in the UK separated Exchange
organisation with internall space and through connector in the states
send a mail for this users in UK. Or if the site in UK will have
separated Internet connection and will use separated e-mail space You
cen set up this as completly separated Exchange organisation - to few
details about Your organisation and bussiness needs. Please post some
more details and somebody will for sure post here some usefull information.
I know that this can be boring but I will post this links once again

becouse I think it can be usefull for You:
