Additional DCs show up as Unavailable

[Andrew LaPierre]

I just found this bug report and the mentioned "workaround" has the second
DC showing as "Online" now. Not sure how long it will last, sounded like it
will drop out if/when there's a connection interruption.

Workaround
----
rm -r /var/log/samba/* ; service samba-ad-dc restart
