The Basics of an NTP Server
NTP servers or Network Time Protocol are devices that connect to a computer network and synchronise all machines to a single time source. Of course most Windows operating systems have an inbuilt NTP program called Windows Time that can synchronise to an Internet time source; however, these can not be authenticated and can leave a computer network open to abuse. NTP servers are normally rack mountable and take up 1U of space but some are built smaller for networks without a dedicated server room.
