When a server with Symantec Endpoint Protection Manager (SEPM) is rebooted, the Manager service fails to load and errors are seen in the Windows Application Event log.
Event ID 3299: The Apache service named reported the following error:
>>> httpd.exe: Could not reliably determine the server's fully qualified domain name, using 192.168.x.x for ServerName .
The server is part of a workgroup and does not have a Fully Qualified Domain Name (FQDN) defined.
If connectivity problems persist for clients, but restarting the Symantec Endpoint Protection Manager corrects this:
Set the Symantec Endpoint Protection Manager service Startup type to Automatic (Delayed Start).
Note: If the SEPM install is Repaired or Upgraded, then the above changes may need to be re-applied.
Windows Server in Workgroup environment.
