Alan,
I hope you get this fixed. Here's what you can get with XP with the MM
timer enabled:
Windows XP LAN-synched to a stratum-1 server, 32s poll for local servers,
1024s poll for Internet backup servers:

Windows XP acting as a stratum-1 server:

Both PCs running "ntpd 4.2.6-o Dec 09 11:48:30.27 (UTC-00:00) 2009 (1)"
from Dave Hart's site. Both PCs have Intel, not AMD processors. Note the
reduced offset on the monthly graphs in week 1 and week 2 - it was so cold
here we kept the heating on 24 hours a day. PC Narvik has been rebooted
about three times since the middle of week 2, hence the three positive
transients.
On PC Narvik, Services Manager, Path to executable is:
C:\Program Files\NTP\bin\ntpd.exe -M -g -c "C:\Program
Files\NTP\etc\ntp.conf"
Now you happen to mention processors, I realise that the PC where the
timekeeping is poor with the more recent versions of NTP (i.e. 4.2.5 and
later) both have AMD processors. Maybe a coincidence?
Cheers,
David
