shared memory driver not working under windows 4.2.7p273++ build?



Hello,
I have a question on the shared memory driver under windows.

I am trying to use the shared mem driver. I believe I am populating the
shared memory segment correctly.

I have the following entry in the ntp.conf file...
server 127.127.28.3 minpoll 3 maxpoll 3 iburst prefer
fudge 127.127.28.3 time1 0.0 refid XPPS
server 127.127.28.2 minpoll 3 maxpoll 3 iburst prefer
fudge 127.127.28.2 time1 0.0 refid XZDA



but NTPD.exe in (debug mode) throws the following error...

C:\Program Files (x86)\NTP\debug>ntpd -D2 -c "c:\Program Files
(x86)\NTP\etc\ntp.conf" > pk.txt
3 Jul 16:28:16 ntpd[5812]: refclock_newpeer: clock type 28 invalid
3 Jul 16:28:16 ntpd[5812]: refclock_newpeer: clock type 28 invalid


i have tried a bunch of ntpd's from davehart.net, but they all throw the
same error. It is as if they do not support type 28 clocks under
windows. Is this correct? If not, what can be done as a replacement
for these drivers, or can they be enabled?

kind regards

Paul Kennedy
