As you will probably have realised, this is an upgrade from an earlier 
version of NTP which used \WinNT\ rather than \Program Files\, so the 
config file was pointing to somewhere other than where the installer was 
expecting.  What I've tried now is copying the ntp.drift.temp file to 
ntp.drift, and assigning it all users, full control.

Perhaps in this case, a fresh install would have been a better idea, just 
adding the servers and logging to the ntp.conf.  The other systems have 
all been a fresh install with your installer, as they have been fresh 
installs of XP made since your installer was released.  I do now vaguely 
recall having to go through this before, whereas your installer handles it 
all for you.

Thanks for your help.
