Hi,
Please go through the below mention path..:
In sep 11 version PTP component is not supported on server OS, But in SEP 12 it is supported,
So you can install SEP 12 or you can uninstall PTP component.
Start --> Control Panel --> Programs & Features --> Select Symantec End point protection (SEP)--> Click Change --> Select Modify --> Uncheck Proactive threat protection --> Click Next --> Finish
It will remove PTP feature.
