NTP server

You can use Timeserv.exe from the resource kit to do this you'll find the details at:

I would recommend W32time instead of Timeserv to serve as your Windows Time Service. It allows you to set you own time internally on a "Primary Time Server" and offers easier set up than timeserv. Also, I believe there are some Y2K problems with timeserv. BTW, the Windows Time Service (W32time) is built into Windows 2000. You can download it free at:
ftp://ftp.microsoft.com/reskit/y2kfix/x86/w32time

It's a service. For lot's of general info and links:

The various time protocols are just ports of TCP/IP, so you don't have to worry that.

Personally, I did not like "timeserv". The version I saw used somerather obtuse text file for configuring, and needed to refer to properties using non-standard definitions, often askew from true standards.

The above link provides several alternatives. I have not yet used W32time. Perhaps it's an improvement over timeserv?
