Device CALS?

**Eclipse2003** · 12-14-2007, 07:21 AM

So I haven't had any experience with Device CALs but I have read some about them. The question I have is, how does one login with a device CAL? Is it the same User Name and Password prompt you get with User CALs? Or is it completely different? Do you login with the computer name instead of an user name? Also, how do you set these up in Active Directory? Do you add Computers instead of Users? Let me know because I have never seen this and when I do run across it, I want to know what I am looking at and how to use it. Thanks guys.

No, CALs don't work that way. You will need to setup a Licensing Server and such, plug in the CALs, and everything else works transparently. Login, AD, all of it is the same. It's transparent. There's a bit to it if you've never worked with it before, so I'll refer you to some MS literature to get you started:

There are two kinds of Client Access Licenses: Per User CALs and Per Device CALs. To quote MS KB823313:

• TS Device CAL: A TS Device CAL permits one device (that is used by any user) to conduct Windows sessions on any of your terminal servers.
• TS User CAL: A TS User CAL permits one user (who uses any device) to conduct Windows sessions on any of your terminal servers.

This means a CAL is assigned to either a machine (Device CAL) or to a user (User CAL). All of this is handled through the licensing server. To get a firm grasp on the subject, read the above excerpt carefully. Remember this is licensing - the only thing it affects is whether or not a user or machine can use/be used for Terminal Services.

So this applies to Terminal Services only? Not to a normal login into a domain?
