Can you help me with my software licensing question?
I'm hoping that someone can clear up a question regarding the ever confusing Microsoft client access licensing.
Reading this page, would suggest that if you bought a client or device CAL and set the licensing mode on the server to 'per client or device' (as opposed to 'per server'), then each CAL would allow that many users or devices to connect to all the Microsoft servers** on the network.
For example, say we have a network with 100 users, 100 clients, and 10 Windows servers, but we only have 50 user CALs (for argument's sake - because I know that isn't enough CALs).
Now suppose I purchased a new server, with a server operating system with another 50 user CALs, does this give all 100 of our users access to all 11 of our Windows servers?
The link above suggests that is the case, however, why is it then, that when I attempt to buy a server with an OEM version of a server operating system, that I can't buy it without CALs?
What I'm actually looking at, is buying a Hyper-V server with Windows Server 2008 enterprise (to allow me to run 4 OS instances), however, I can't seem to purchase Server 2008 enterprise with any less than 25 CALs. Why is this?
** = To the type of server the CALs belong to (e.g. Server 2003 or Server 2008 - but not both)
