NTP+PPS works just fine on XP/32 and Win7/32.
Here is what i have on ntpq -p

remote           refid      st t when poll reach   delay   offset  jitter
oGPS_NMEA(1)     .GPS.            0 l   72   16  360    0.000    0.108   0.008

Unfortunately, when I test it on Win2008 R2-64bit, PPS driver does not start. 

I followed instructions on and did all the steps carefully, but it keeps failing.

My configuration is as follows:
server minpoll 4  #PPS
server  minpoll 10 maxpoll 10 mode 16  prefer  #GPS,BAUD:9600
fudge flag1 1 flag3 1 stratum 0

Here are some screenshots:

1.	The windows event log states NTP error messages

2.	Environment variable setting

3.	COM1 driver details for Serialpps.sys 

i think the serialpps is not working, so I tested different driver versions, but none worked!

Maybe I missed something along the way?

1-Is the "not digitally signed" normal in screenshots 3??
2-Any one tested PPS driver in win64 successfully?
