Hi all,

We are an outsourcing company providing call centre's and hosting services.
our main building has just over 10 call centres supporting 20-40 seats in each one.
this is also the site of our small data centre.

we have a domain structure as follows:

servers infrastructure at this level           |
core management at this level                  |
- - - - - - -  --  -  -- - - -- - -- - - - -- - -- -   -  - - - - - - - - - - -- -  - - - - - - - - - - - - - -- - - - - - - - -
|                           |                                |                                             |                             | .   .    .    .   .
|          centre1.company.local    centre2.company.local    centre3.company.local         etc....
company staff (management,it support,sale,directors)

Each division will be on seperate vlans, server infrastructure on sepearte vlans too

Echange - if we were to give each centre email services where would we place exchange? and can it be set up for seperate public domains - eg. user1@company1.com user32@company5000.co.uk etc...

Please let me know your thoughts on the set up and if you can reccommend any improvements changes?

Many Thanks!

I wouldn't use separate Active Directory domains at all.
I would  create a generic NETBIOS name at company.local and have all the users who work for different contracts log on using their UPN rather than domain\user formats. That keeps everything separate.

Doing it the way you've drawn out costs a hell of a lot of money in server infrastructure, less if you're running VMware but it's still a lot of instances. You need two GCs in every single domain so my suggestion means two servers/licenses and your idea requires at least four, even for just one customer.
There are a number of ways that you can configure your envrionment but everything depends on your security requirements etc... there are a number of factor why you can go with a single domain vs multiple etc....

I will just focus on Exchange since that is your main question.

Truth be told you can put Exchange anywhere and all users can have access to it..

If you are going to be hosting it would be a good idea to have Exchange in a seperate AD site with dedicated DC/GC which will help with directory access

If you are hosting have planned your clusters , dr, do you provide site failover, etc......

planning a hosting center and setting it up properly it a HUGE undertaking if done correct.

I would recommend you pay some $$ and bring a solution provider in to assist with at minimum your design.
