SNTP Service (64-bit) is a synchronization client or server for the more advanced user wishing to maintain network time synchronization and services under 32 bit versions of Windows XP, Server 2003, Vista, and Server 2008. It is an effective tool for the desktop and also includes important features to support deployment in enterprise networks. From a single workstation, the administrator can remotely configure, monitor, troubleshoot, and track licensing of enterprise-wide SNTP Server client and server components. This product incorporates full SNTP client and server function in complete compliance with RFC2030 - Simple Network Time Protocol. It adds tools required in the enterprise and builds on the experience and time tested algorithms developed for YATS32 without carrying forward the legacy features required by a desktop Windows 9X application.
