LiveUpdate Administrator (LUA) is used as a central point for content downloading in the company. Symantec Endpoint Protection Manager (SEPM) is configured to download definition updates from LUA.
When LiveUpdate is manually executed on SEPM, contents get updated. Schedule LiveUpdate on SEPM is however failing with error code 4, because it tries to reach Symantec LiveUpdate servers and there is no Internet connectivity on SEPM.
Settings.liveupdate shows Symantec LiveUpdate servers as HOSTS. Reinstall LiveUpdate did not help.
Release Notes show there is a known defect fixed in RU7 MP1, but both SEPM and clients are already using this build of SEP.
"Error: LiveUpdate encountered one or more errors. Return code = 4" in LiveUpdate status in Symantec Endpoint Protection Manager
Generating a client settings host file for Windows LiveUpdate clients on the LUA 2.x server and placing it into the SEPM's LiveUpdate folder is one method for ensuring that both the SEPM and its SEP 11 client will retrieve materials from the LUA server.
