The two "Yes"'s there are wonderful to read. We're going to pretend that
you didn't add the 'I suppose so'.

This introduces another question for which I suppose I should start
another thread but there may be some relevance here.

I think we're making the wrong decision given 2 boxes to make the
domain. We're using the more powerful box with the bigger disk as the DC
but it sits there with hardly any load all the time. The member server
hits smbd hard all day. top gives high %CPU and %MEM a lot of the time,
especially when we're doing photos. It doesn't seem to slow things down
much and the other thing we see is that when everyone logs on at the
same time, it's slow. The latter is the DC but it still doesn't show
much activity. Could that be because it's reading the profile for
windows and the home folder for Linux?

Are there any guidelines for this sort of stuff?
