The LiveUpdate Administration Utility 1.x and, later, the LiveUpdate Administrator 2.x were developed to address the two major concerns of network administrators: high levels of external traffic caused by users using LiveUpdate, and network security. LUAU and LUA allow an administrator to modify LiveUpdate so that network users can download program and virus definition updates from an internal server instead of the Symantec LiveUpdate server over the Internet.

Latest version of LUA 2.x

LiveUpdate Administrator 2.3.2 has now been released.  For details on new features, please see LiveUpdate Administrator 2.3.x: Release Notes.  Please contact Symantec Technical Support for details on how to obtain LUA 2.3.  Additional articles on LUA are linked, below.

This version provides compatibility with Symantec Client Security 3.0 and replaces previous versions of this utility.
