The general believe, Remote Desktop Services licensing isn’t very difficult to implement. If you have a licensing problem verify this by checking the EventLog on your Terminal Server, following this checklist should solve most problems:
- Do you have a Terminal Services Licensing Server installed and activated?
Note that you always need an activated Licensing Server, even when your TS runs Windows 2000 and all of your clients run W2K Pro, XP Pro or Vista Business. - Can the Terminal Server located the Licensing Server?
Again, the EventLog on the Terminal Server will tell you if you have a Licensing Server discovery problem. If that is the case, use KB article 279561 (for 2003) or 239107 (for W2K) to fix it.
If you run 2003 SP1 or later, you can also set the preferred TS Licensing Server in Administrative Tools – Terminal Services Configuration – Server Settings, which will create the registry entry described in KB 279561. Or use a GPO setting to define the preferred licensing server, but be sure to apply the hotfix from KB 922508 (included in SP2) first. - Do you have enough available TS CALs on the LS for every client or user that needs one?
Note that every client or user needs a purchased 2003 TS CAL when connecting to a 2003 TS. - 2003 and 2008 only – If you installed Per User TS CALs, is the Terminal Server configured to use the Per User licensing mode?
You can check this from Administrative Tools – Terminal Services Configuration – Server Settings – Licensing Mode
If it’s set to Per Device mode, it will request a Device TS CAL from the LS. And since the LS only has Per User TS CALs, it will issue temporary Per Device TS CALs, which will expire after 90 days. In Windows 2003, your Per User licenses are listed as “Not Applicable” (N/A) in the Licensing Manager. That’s because Per User licenses are unmanaged in Server 2003, as documented in KB article 822134, and won’t be issued at all. - You will have to keep track of the total (not concurrent!) number of connecting users by hand. This is changed in Terminal Services Licensing for Windows Server 2008, which provides Per User TS CAL tracking and reporting.
UPDATE: The RDS Team developed a Per User CAL Reporting Script to help with this task.
