When trying to start the Symantec DLP services, the following error is displayed:
"An error 1069 - The service did not start due to a logon failure"
Check with your System Administrators as there could have been a reset of the Local Policy on the System which could cause an issue.
Check the login-as-a-service rights as they may have been removed from protect and protect_update accounts.
Then manually re-enter the credentials under the Properties of the services for those accounts for each service and start the services.
