Synchronizing Time with NTP
Synchronizing time with other servers can benefit an organization, allowing for better coordination of log files and helping with time-sensitive services like authentication. In this hands-on lab, we will be deploying a Network Time Protocol (NTP) server to use both an Internet NTP server and a peer NTP server on a subnet.
