Oh well...

That didn't change anything either, other than the registry setting type 
is now 'REG_EXPAND_SZ' like yours, the com port properties still show 
the original MS serial.sys file as the driver, and NTPD is still 
resolutely using usermode PPS timestamps as a result.

(Yes, I did reboot the thing.)

The next step could be to swap the contents of the original serial.sys 
and serialpps.sys files, if it insists on loading the former, I'll try 
force feeding it again, but the last time I tried that (in error) I got 
into a black screen/reboot loop...   So, I need to get the physical 
situation here again such that I can swap hard drives about to restore 
the file if that comes back.

Does anyone know of other reasons why a Win2000 system will not accept 
and act on these changes?   I'm using COM2 for the GPS, nothing is using 
COM1 (at the mo') & there are no other COM (virtual or otherwise) ports 
on this box (a Compaq Deskpro EN small form factor desktop.)

The faded grey cell is somewhat frazzled again, so all that can wait a 
while, as Faros *Needs* this thing right now, as even as it is, it is 
just sooooo much better than the WAN service at this time, currently 
variable and anything up to 300ms or more latency to the "nearest" NTP 
servers out there!

I think I need to lie down in a dark room for a while.
