Technically the w32time.exe service is an SNTPv4 compatible
service.

I think though that an XP box joining an AD domain performs
a negprot request to get the current time before issuing
the AS_REQ to be able to compensate for clock skew.
I'll admit that's clever.  That might be a little hard
to hook into our client code right now though.  I can
live with the the currentTime attribute from the rootDSE
for the moment.




cheers, jerry
