This article describes issues related to client access license.
There are two different licensing models that customers can choose, either a per server or per seat. The per server licensing (concurrent licensing) will cause Windows NT to implement a concurrency check to only allow the number of concurrent file/print users as configured in license manager. Per seat licensing does not implement the license manager check, though the customer must still purchase a client access license (CAL) for such clients.
The following uses require a CAL:
Note the following general exception to Windows CAL requirements. Windows CALs are not required when access to the server software is unauthenticated and conducted through the Internet. Authenticated access is defined as an exchange of user or application credentials between the server software and a user or device. An example of this exception is if unidentified users browse your public Web site. Windows CALs are not required for those users.
