Dual Domain Servers Running Server 2008... User CAL Question

We are setting up 2 Domain Controllers both running Server Standard 2008. Say we have 50 active users in the network. When purchasing server software and CALs, do we need to purchase 50 CALs for each server licence? Or a total of 50 CALs for the network and will the servers share them?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Depends on the licensing model you choose per server or per seat.  

In per seat you would need one CAL for each user only so 50 Cals.

Disclaimer:   You can talk to 10 Microsoft Licensing experts and you will get 10 different answers.

If you use User CAL licensing then you need 1 CAL per user.  You could have 100 Servers or 1 Server.  The CAL's for user allow them to access any Windows Servers.

If you use Device CAL licensing then you need 1 CAL per device (Any device -tablet,notebook, PDA, etc) that connects/accesses the server.

Example.  You have 50 computers at your office but have 70 users.  It may be better to use Device CAL's so that 70 people can share the 50 computers.  

Also, Windows CALs are not the same as Exchange, SQL, etc. Those other products have their own version of CAL's that you would need in addition to the Windows CAL's
