Great.

Well, it appears you are correct:

Geez, Microsoft sux.
However, I *wonder* if XP64 is more like NTServer2003, than it is like
XP32. That is, on XP64, does the LocalSystem account in fact HAVE all
the necessary privileges, as it would on XP32 --- or can you only call
LogonUser and friends from a special account on XP64, a restriction
common to NTServer2003 and above?
Can you *manually* remove the service (cygrunsrv -R tftpd), and then
*manually* re-add the service running under LocalSystem:
TFTPBOOT=/var/lib/tftpboot
args_value="-L -c -p -u tftpd -U 022 -s ${TFTPBOOT}"
cygrunsrv -I tftpd -d "CYGWIN tftpd" -p /usr/sbin/tftpd -a "$args_value"
-y tcpip -e CYGWIN="${csih_cygenv}"
and restart the service. See if it actually runs -- AND, make a large
transfer and use 'ps -eaf' to see if the spawned child tftpd is running
as LocalSystem or the 'tftpd' user.
If the latter, then we know that LocalSystem can in fact change UIDs --
and I should update csih so that is_nt2003 is a little more
discriminating, and doesn't lump XP64 in with them.
If it *doesn't* work, then...well, The Right Thing To Do is to fix
is_nt2003 as described above, and then change all the tests for "gee I
need a special privileged user" to
if is_nt2003 || is_xp64
but that would create a LOT of ripple: every client of csih (cron, exim,
openssh, inetutils, etc etc) is probably already using is_nt2003 for the
same reason and they'd all need to change. So...I think I'd just
declare victory, leave is_nt2003 alone (and wrong), but update the messages.

No hurry. I'm booked up for a few more days anyway.
