For starters, OpenAFS is not a local file system like NTFS.  It is not
something that can be installed on local disk and then exported using
CIFS to OSX clients.  The OpenAFS Windows client and OSX clients are
file system clients that provide access to file system storage servers
from dedicated AFS file servers.  You could build an AFS cell (volume
location database, protection database, and a fileserver) and use your
existing Active Directory as the Kerberos realm.  Then install the OSX
OpenAFS client and copy your data to your
/afs/local-cell/some-volume-path/.  By installing the OpenAFS Windows
client on a Windows Server you could then access the data in
\\afs\local-cell\some-volume-path\ to copy the data to the local disk.

However, if all you need is a one time copy I would suggest using an
archival tool such a zip, b2zip, 7zip, etc. to compress the entire tree
of files into a single file and then copy it directly from OSX to the
Windows Server via CIFS.
