In Symantec Endpoint Protection 11.x and 12.x Small Business Edition, TruScan (also known as Proactive Threat Protection, or PTP) is not compatible with any version of Windows Server operating system. Symantec recommends omitting TruScan/PTP when installing the product on these operating systems; if installed, the product status will be displayed as OFF
Hi,
The reason is on Windows server operating systems and Windows XP 64-bit operating systems, Proactive Threat Protection only supports Commercial Application List scanning or "CAL". This is why the status shows as "OFF" in the client interface.
