A client of mine just purchased a New DELL with SBS 2003 R2 preinstalled. It came with 5 User CALs. He then purchased 15 more but got device CALs . Is there a way to manipulate the combination of User and Device CALs so all of his office workers can access the server and use email? He has a total of 18 users who logon to the network from the same PC.
