Trying to understand this, without any of Louis's suggestions in place,
then if DC1 disappears, authentication stops and there is nothing in the
logs on DC2. With Louis's suggestions and if DC1 disappears,
authentication still stops, but you get log messages on DC2.
Is the above true ? If it is, it is pointing at a problem on DC2.
