asked on

what is the best way to implement a new domain for joint project involving 3 seperate companies

we have a new job coming up the will require an IT setup
it will be 3 offices that need to be connected to each other with a total of around 120 users
i was going to install one server and have all users connected to it
around 40% of these users are people who are only going to help out for around 1 year and they have their own laptops currently connected to another office domain.
what is the best way to setup the IT infrastructure to include these users
should i use child doamins or domain trusts etc

I would use trusts for the domain that will be gone in a year and a child domain for the other users.

i need to setup a new domain called domain c
domain c will consist of 100 users
but i have some users who belong to domain A who will need to access domain c for file server data etc and some users from domain  B who will need to access domain c
only some users from domain A & B may access domain c and the main users who are only on domain C may not access anything from Domain A or B
How can i achieve this?

if i create the trust level will this not mean all users in domain a can access c
can i limit a trust to group of users
Yes you can assign the group permission to user so that you can limit a trust to group of users.

Assign domain A and B domain user group permission Universal group or Global group who wan to access domain C and remain user assign permission domain local .  You are going create External Trust Nontransitive One-way so that C user can't access A and B resource.
