[ntp:questions] Synchronizing against a free-running server

We have been trying to convince ntpd to synchronize with a free-running
windows server (why one would want to do this is another question, suffice
to say there are political reasons).

However I have not been able to convince it (neither 4.2.6p2 on debian nor
4.2.4p8 on centos) to do this. The moment the windows server is set to
sync to anything (pool.ntp.org, some other server, ...) it works. But
as long at the server advertises itself as 'stratum 1, .LOCL.', ntpd seems
to ignore it. Tried to force it using 'server 10.x.x.x true prefer', and
setting all other server lines including the local fall-back to
'noselect', no dice.

Any hints appreciated.
