Server CALs allow users to connect to services (ex File Shares, Printers, IIS Sites).

TS CALs allow users to RDP into TS Sessions on the server.

but I can do file shares for free with any xp desktop, why would I need to buy licenses to share folders that are on a win 2k3 server? – Detritus Maximus May 12 '11 at 13:46
XP Desktop is restricted to 10 concurrent users and has an extraordinarily limited set of file sharing capabilities compared to Server 2003 (which is also very limited compared to Server 2008 & R2). – Chris S May 12 '11 at 13:48
