Here is what we currently have :-
30 SBS 2003 CAL's
Microsoft partner program where we have the following server products available :-
SBS 2003 R2 Premium
Server 2000 standard
SBS 2008 Standard
Server 2008 standard
The original plan was to install SBS server as the main domain authentication server and link a Linux Samba server to it to be the main file server. No problem with that as that is the exact CAL's we purchased.
We would like a 2nd server to be a backup incase the first failed so that at least people could continue to log in and for authentication to carry on working.
What choices do we have for the backup server without having to buy more CAL's?
The SBS features are really overkill for what we need as we dont use the firewall feature or exchange.
