[ale] Linux Bind9 and Windows .local dns?

Corp is using .local for some internal services such as a key file server.
I have no control over it.

  The first key issue I'm seeing is a windows box on my 172.27 subnet can
ping the file server but trying to do a dns lookup on the hostname is
failing to resolve.  As a result all the procedures that tell my
manufacturing users to open "\\share.local\Manufacturing" fail and updating
them to do \\10.bbb.ccc.ddd\Manufacturing" would cause a lot more pain than
it's worth.

  My Linux bind server has the windows domain servers as the upstream dns
in my resolv.conf but I've never had to deal with this type of forwarding
before so I'm not sure where the breakage is.

  Unfortunately we have critical documents on the shared server and I need
to get it working this way.
