After changing the following settings in xmlmodifier and trying to scan a file the Symantec Protection Engine service would stop and display Error: unable to connect to the Symantec Protection Engine.
xmlmodifier –s //policies/ThreatPolicies/ActiveContentScanning/@enabled True policy.xml
The value was set to True instead of true with a lower case t.
xmlmodifier –s //policies/ThreatPolicies/ActiveContentScanning/@enabled True policy.xml
To fix this issue run the command below and restart the Symantec Protection Engine service:
xmlmodifier –s //policies/ThreatPolicies/ActiveContentScanning/@enabled true policy.xml
