what is the best practices for the number of DC our enviroment
Hi all
we have around 800 users and 4 VMs act as exchange servers 2010 sp3
so we have 4 physical servers run as active directory domain controller 2008 R2 plus DNS and the same number as VMs that mean we have 8 DCs
i want to reduce the number of DCs but my colleague said NO it is important to have many DCs to serve the users and exchange activity .
is this true and why and what the best practices in such case
please if you can provide an article or doc talk about such case
thanks in advance

Well , you should refer the IPD - Active Directory Domain Services from Microsoft, to understand the number of DCs require. I have attached the files for you. Refer them to clarify your doubts.
As stated by @Amit, keep at least 2DCs in each site provided they should be powerful enough. I do keep 3 in each site, since I have a lots of AD integrated applications running in the net work + all of them are GCs too.

thanks for advice
we have 2 new physical servers act as DC i will connect to one of them and change the operation master . i will change the RID - PDC - infrastructure to one of them and this server will the primary one . then i can remove the rest normal using dcprmo right ?
then i will get no effect ?

That is fine if you keep Domain Name master and Schema master on one server and rest FSMO role son another server.
you can remove using DCpromo without any issue, just keep checking replication time to time and I would suggest demote one DC only within 24-48 hours to see if there is any impact.

thanks again
for example i want to dc1 and dc2 as physical DC servers
i want dc1 to have all roles plus DNS master and DHCP master
so i found out how to move
from dc3 to dc1 these roles
1- RID Master FSMO Role
2- PDC Emulator FSMO Role
3- Infrastructure FSMO Role
but i dont know how to move these roles to DC1
1- Schema Master FSMO Role
2- Domain Naming Master FSMO Role
because as i said i want DC1 to be everything plus DNS master and DHCP master
so please tell how step by step or provide some links for me
thanks
