Environment
DLP 15.x
Cause
This is caused by the executing JRE instance (java.exe) being unable to locate (a correct) sunsec.dll.
Resolution
This may happen if the environment PATH has a reference to a different JRE than the one that the Symantec DLP Manager service is running. Remove JRE directory references from the environment PATH variable that are not to the path that the Symantec DLP services are using.
