This package contains the HP Consolidated Client Infrastructure Session Timers (HPCCIST) Software for the listed desktop models and operating systems. The HPCCIST software emulates the Terminal Services session timers found in the Microsoft Windows 2003 Server Operating System. When running the Microsoft Windows XP Professional Operating System and connected to a domain, the built-in Windows XP timers do not work as expected. The HPCCIST software provides the expected functionality. These timers may allow more efficient allocation of blade PCs in environments where there is not a one-to-one ratio between clients and blade PCs. For additional information, see the "HP CCI Session Heart Beat User's Guide" included within the package.
