5.5.3 License Problems
For remote administration, licenses come built in to the Windows Server 2003. The Terminal Server role,
however, requires the installation and proper configuration of the terminal server licensing component.
Because of this, license problems typically relate only to the terminal server role. If you have license
component problems you will receive one of the following error messages:
• The remote session was disconnected because there are no terminal server client
access licenses available for this computer. Please contact the server administrator
• The remote session was disconnected because there are no Terminal Server License
Servers available to provide a license. Please contact the server administrator
These error messages can indicate several issues which must be resolved systematically. First, verify that the
license server is online and able to communicate on the network. Also verify name resolution during this
step. Next, ensure that the license server component has been activated. Check event logs on the license
Verify that the license server has a sufficient number of valid client licenses for your network, and that the
licenses are valid. The Terminal Server draws licenses from the license server so you should also ensure that
these two servers can communicate with each other.
Finally, check the clients. It is possible that the clients never received a valid license. By default, clients
often receive temporary licenses that expire after 90 days and prevent further connections. If they did
receive full licenses, the licenses may have become corrupt and need to be replaced or overwritten.
