deployment and for on-going management of the thin clients in your
organization. Each HP Compaq thin client is recognized by the Altiris
Deployment Solution as a supported device. As a result, you need not
track license compliancy for each device. For additional information
about the Altiris Deployment Solution tool, refer to the Altiris
Deployment Solution insert that shipped with the thin client and the
Deployment Solution User Guide that is available at:
www.altiris.com/documentation.
The next sections describe the features of the t5720/t5725. For a
