Purchased 2 SBS 2003 Standard Edition for our new Dell Server(10 cals). Needed 11 licenses, so we bought Small Business Server 2003 R2 which had 5 CALs. Installed the R2 on the server and then went to add CALs from the Standard Edition packages. I used the Product Key info from the back of Case 1, but Server says these are invalid. What have I done wrong? Newbie to this forum.
