What precision do you want? I have some plots of what I see on my Windows systems here: http://www.satsignal.eu/mrtg/daily_ntp.html I have three stratum-1 servers based on Windows-2000 (Bacchus), Windows-XP (Feenix) and Windows-7 (Stamsund) all driven from Garmin GPS 18 LVC devices. If you needed a better stratum-1 server I would recommend a FreeBSD-based system. One Windows-XP system is synched to two of those stratum-1 servers, and that is the PC Narvik. You can see that it keeps within about 3ms of the correct time, and the offset has a strong periodic component because of the temperature variations in this "domestic" environment. If within 3ms isn't good enough, one approach might be to get a GPS 18LVC or other GPS receiver with a PPS (pulse per second) output, and building a box which would drive all the PCs you need with an RS232 signal derived from the PPS source.
