When Log Server is unable to contact Policy Server, the service stops. To address this problem:
Steps
Make sure that the Policy Server service associated with the stopped Log Server instance is running.
Verify that the Policy Server IP address and UID that appear in the websense.ini file on the Log Server machine are correct.
The websense.ini file is located in the bin directory (C:\Program Files\Websense\Web Security\bin, by default).
The UID in the websense.ini file should match the one that appears in the config.xml file in the bin directory on the Policy Server machine
(C:\Program Files\Websense\Web Security\bin or /opt/Websense/bin/, by default)
