Network Time Syncronization via GPS?

TrAvELAr asks: "I run a rather large network for a research company and I have been tasked with a project to ensure that the time is accurate on all of our studies. Right now, I am using the time service built into Windows 2000 to sync all of our workstations with one of our servers. My problem lies in the fact that I can't prove that the time on my server is accurate. Because of the nature of our research, our network is not allowed to access the internet, thus ruling out synchronization to NIST and other time servers. I've been toying around with the idea of syncing it via GPS. I've done some research on the net and found a couple of places that offer packages for this at a fairly high price. I believe that this is something that I could do myself if I could find the right interface software. Has anyone out there had any experience with this type of project? I would appreciate any feedback/suggestions from anyone out there who has implemented/maintained a similar system."

that comes bundled with Win2K. Configure the service to start automatically (it's set for manual start by default), and use net time /setsntp to set the NTP server(s) you want to sync to.

You can select one machine to be the master server for your network -- set its NTP server to one on this list, and enable it as an NTP server (some registry setting I can't remember). Then set the other machines (via the net time /setsntp cmd) to use your time server.
