Vista and Windows-7 can be tamed, and I am seeing about 25 microseconds 
averaged jitter on two Windows-7 stratum-1 servers right now (PCs Alta and 
Stamsund).  This is not as good as the 2.5 microseconds averaged jitter on 
the XP server, Feenix, I agree.  You can see my current results here:


(Note that the FreeBSD PC Pixie was on and off yesterday for NTP updates 
and a reboot).

As far as I am aware, serialpps-ppsapi-provider.dll  can live anywhere on 
the PC (provided you set the environment variable which points to it), but 
in my case the \Tools\NTP\ tree is an obvious location.
