Network Time Protocol (NTP) is the default time synchronization protocol that is used by the Windows Time service in Windows Server 2003. NTP is a fault-tolerant, highly scalable, time protocol that is used most frequently for synchronizing computer clocks. It does this by using a designated time reference. Communicator Phone Edition requires NTP to set the correct time and date for Communicator Phone Edition.
