Symantec Endpoint Protection Manager (SEPM) is unable to access a remote resource. The "...\tomcat\temp\index[X].html (The system cannot find the file specified)" messages generally indicate that the SEPM is not able to access current Symantec threat information over an Internet connection.
In another instance, the SEPM points to the internal LiveUpdate Administrator 2.x (LUA 2.x) server to download the definitions and the index file is never cleared on the SEPM.
To verify, try browsing to "http://securityresponse.symantec.com/avcenter/venc/auto/index/indexA.html" and check for the return of any text.
