This step-by-step article describes how to either deactivate or reactivate Terminal Services Licensing on a server that is running Windows 2000 Server or Windows 2000 Advanced Server. You must activate a license server before it can issue licenses to Terminal Services client computers. Use Terminal Services Licensing to activate a license server. When you activate a license server, Microsoft provides the server with a digital certificate that validates server ownership and identity. If you use this certificate, a license server can make subsequent transactions with Microsoft to receive client licenses for the servers that have Terminal Services enabled. Terminal Services Licensing has already been installed and activated on the server.
You may need to deactivate a license server if the certificate of the server has either expired or become corrupted, or if you redeploy the server. You are prompted to reactivate the license server when its registration has expired.
You cannot deactivate or reactivate a license server by using either the fax or World Wide Web connection methods.
When you use the telephone to reactivate a license server, you receive confirmation that the license server has been reactivated from over the telephone.
When you use the telephone to deactivate a license server, you receive a confirmation code from the Customer Support representative. Type this code in the appropriate space in the Licensing wizard.
If you reactivate a license server, a record of your license is retained. Licenses that were already issued remain valid. If you have any unissued licenses, these licensed are also valid, but they must be reissued by Microsoft.
When you deactivate a license server, you cannot license additional client computers from this server until the license server is reactivated.
