The software is free--it's a port of the official NTP reference code, and the puck only ran us $80. Depending on the shop that ultimately hosts a Hyper-V server, this is just coffee money.<br /><br />It works very well while still preserving the NTP.org pool for backup and cross-checking.<br /><br />We have all our servers, and selected clients, using our in-house GPS server plus three of the pool servers.<br /><br />(The adventurous people can get the code from ntp.org; it does build in Visual Studio and would run nicely in a Hyper-V host; my personal NTP box is an ARM appliance, a story for another day.)<br /><br />I also love a third-party control panel applet called W32TMDT. This is a friendly way of configuring the Windows time service, and also a great diagnostic tool for comparing different time sources on any one machine.David Moisanhttps://www.blogger.com/profile/15246027784687332011noreply@blogger.com
