Hello,<br />
I am going to use the transition pack to move my SBS 2003 server to server 03. &nbsp;I will alco purchase the needed CALS to transition.<br />
My question is after this transition is all done I want to now add a second domian controller, also server 03 with exchange loaded on it.<br />
How do the CALS work in that situation? &nbsp;I will have enough cals on one server for all my users.<br />
On my new machine I will have it loaded it exchange as well so I want users to be able to connect to both servers. &nbsp;Do I need to add more cals to the second machine?

Hello,
I am going to use the transition pack to move my SBS 2003 server to server 03.  I will alco purchase the needed CALS to transition.
My question is after this transition is all done I want to now add a second domian controller, also server 03 with exchange loaded on it.
How do the CALS work in that situation?  I will have enough cals on one server for all my users.
On my new machine I will have it loaded it exchange as well so I want users to be able to connect to both servers.  Do I need to add more cals to the second machine?
