Issue/Introduction

SymantecDLPDetectionServerService service shows not started after rebooting the server. Closer inspection shows that the service attempted to start, but the domain account wasn't able to authenticate so the service immediately stopped.

Environment

Release : 15.7

Component : Default-Sym

Cause

The Domain Controller was unreachable immediately after rebooting the server. 

Resolution

There are a few ways to resolve the problem.

1. Resolve the issue with the network so the DLP detection server can reach the domain controller on time
2. Delay service start
3. Manually start the service after the server comes online
