Thanks, Martin.  A lot of things in Vista now require more priviledge than 
before, at least when run from a user-mode program.  It could be something 
as simple as ensuring that you only try and access the HKLM part of the 
registry with read-only access.

By the way, I am seeing rather poor performance of NTP on Vista, and yet 
Heiko (?) reported good performance earlier this year (IIRC).  Any tests 
done at Meinberg?  Here are my results:


Periods of stability and periods of oscillation.  Why?  The service is 
started as:

C:\Tools\NTP\bin\ntpd.exe -M -g -c "C:\Tools\NTP\etc\ntp.conf"

on that system - the image path in HKLM\CurrentControlSet\services\ntp\.
