Home and Monitors tabs don't work correctly if TEMP and TMP environment variables point to different folders
Fix ID: 1177149
Symptom: Accessing the Home or Monitors tabs brings up a blank page when the TEMP and TMP environment variables point to different folders.
Solution: Instead of relying on the TEMP and TMP environment variables, Symantec Endpoint Protection Manager now uses a custom folder for the temporary PHP session files that are used when accessing the various tabs from Symantec Endpoint Protection Manager. The new custom folder is located at: c:\Documents and Settings\All users\Application Data\Symantec\Symantec Enterprise Protection Manager\PHP\temp.
