I'd double-check the c5 ntpd config. Are the xp machines really in the same allowed subnet like the c5 workstations? Personally I don't use Windows' time sync anymore, I use the ntp implementation for windows from here: http://www.meinberg.de/english/sw/ntp.htm Install/config is very easy, you even get the ntpdc command.
