My client has SBS 2003 with 15 licenses. There are only ever up to a maxiumum of 15 users connected to the system but frequently the server will report that licenses have been exceeded. There licenses installed are 15. I've noticed in the security logs that on some machines the machine logs on and also the user. WIll this be the cause of the license warning, and if so, how would I stop the machine logging on and using up a license?
Many thanks.

    That all depends on whether the additional 10 CALs that were purchased were USER or DEVICE CALs.  Plus, the "maximum of 15 users connected" has nothing to do with the amount of CALs needed.  Simultaneous connections do not determine the amount of CALs needed, but rather a CAL is needed (depending on whether you buy USER or DEVICE CALs) for each user or each device that connects at any time.

    The original 5 CALs that come with SBS are either/or which provide a bit of flexibility.

    You don't "stop" the machine from logging on, you just need enough of the right kind of CALs.  Most of the time USER CALs are what is used.  About the only time you would want DEVICE CALs is if the company has shift workers where many people use the same computer.

    Assuming that you have USER CALs already, then the question is how many users are there that use the network?  I would think that because you stated that there are only ever up to a maximum of 15 connected that perhaps there are actually more users than that?  Perhaps you should have DEVICE CALs instead?

    Hopefully this will help you understand SBS licensing a bit more:

    let's say we have 15 USER CAL's  - then if I have 20 users set up an the system and they each connect and then logoff before the next. WOuld I get a warning when the 16th user connects OR only when the 16th concurrent connection is made?

    Accepted Solution

    If you have 20 users set up in the system (other than the builtin Administrator and one other designated Administrator) you would need 20 CALs.  I tried to be rather clear above that concurrent connections are not a factor with SBS.

    SBS licensing is rather fuzzy and pretty lenient to allow you some flexibility.  Since it's not an exact figure that you can read on a report, the requirement is that you need to have enough CALS to cover your usage of the server... it's just YOUR responsibility to MAKE IT SO.

    So, If you have 20 users, you need 20 CALs.  Don't try to over analyze this... it's pretty simple... have enough CALs and then you don't need to worry. (and considering a 5-pack of User CALs runs about $279 these days, it's a pretty good deal as well!)
