We are about to purchase CALs for server 2008. We have two domains each in their own forest. One domain is for student use and one is for staff use. (seperated for security reasons) we have around 500 devices and around 1000 users (staff/student). Staff a user account on the student domain. We tend to map the public area on the student domain so that staff can drop files for students to work with. They also have their home folder on the student domain mapped to their staff domain laptops.
We will have two DC's (that will also perform other roles like file/print)
Having studied the 70-290 i know that if we go down the per server licence mode, we would need cals for each server. So i have looked at device cals which seams to be the more economical option.
However as staff will be accessing two domains will we need two sets of device cals if they access the two differnet domains. Or is it just one set required. I ask as i have been in touch with two places and they both replied with two different answers.
