A modification has been done to a Symantec Protection Engine (SPE) configuration file e.g configuration.xml, filtering.xml, liveupdate.conf, liveupdate.xml by directly editing the configuration file with notepad or any other non xmlmodifier application.
The configuration file has been edited with a non-xmlmodifier application and has lost the java parameters.
Before editing any SPE configuration file pls ensure you back up the existing configuration file.
It is necessary to use the xmlmodifier application shipped with Symantec Protection Engine.
Since we can not guarantee configuration file format consistency when using any other method to modify the SPE configuration files.
For SPE 7.0.x
java -jar xmlmodifier.jar -s XML_PATH
For SPE 7.5.x
xmlmodifier.exe -s XML_PATH
At this time the only confirmed solution is to reinstall Symantec Protection Engine.
In most cases restoring the original xml file and restarting the scan engine service will restore the service and console access.
Symantec Scan Engine 5.2.x
Symantec Protection Engine 7.x
