Windows 2003 Server SP2 Standard edition User CAL’s question

Hello,

We have a Windows 2003 Server SP2 Standard Edition O/S which came with 5 User CALS. We want to buy 5 more user CALS. Where can I buy more of these from?

I believe the O/S was bought online from either TigerDirect or NewEgg and came with the 5 licenses. I don’t see on these sites where I can buy more licenses.

I live in Canada and I want to buy 5 more licenses. Can I get these directly from Microsoft or do I have to buy them from someone else?

Thanks,

Charles.
