CAL, User, Device, Help!!!

In addition to the base Server Operating System license, you need to purchase Client Access Licenses. These license each connection by a node (a user or a device) to access the server and its resources.

CALs can be bought in two forms - a "User" CAL licenses one person to access the server from ANY device. A "device" CAL licenses ANY user to access the server from one device (workstation, PDA etc.). You don't state how many users will be hung off the server, so I can't tell you which approach would be the most suitable for purchasing CALs. The usual approach is Per-User CAL licensing though, as that will allow the users to connect to the server from any PC.

Hosting a web site available to the public anonymously does not require CAL licenses; CALs are only required when authentication and credential exchange with the server takes place.

So i need them even if i use a simple 2003 domain?
And if i have a server without domain?

The Active Directory configuration of the server does not affect this, nor does the complexity of the domain configuration. If a user is authenticating to the server, that session NEEDS a valid CAL.

This applies even if the server is not in a domain but a workgroup, since user's will still authenticate to the server through local user accounts.

What you mean "local user accounts"....and if is a domain account hosted on serveR?...LOL..this is my last question about it!!
