Re: What "secure" file transfer products do you use on Windows?

[Russell Fulton <r.fulton () AUCKLAND AC NZ>]

Thanks to Joel et al who have pointed to winscp....

Sorry, I need to clarify -- I'm looking for a server that allows one
to transfer files from an MS host (i.e. an ssh2 capable server).  I
know and love winscp :) but unless I have missed something it is an
sftp client, not a server.  I need to transfer files securely between
two windows servers.

I know about http://www.freesshd.com/ on the free side and 
http://www.bitvise.com/winsshd?gclid=CPKJ6ovJ8ZgCFQ9JagodvBhK2A
 on the commercial (but reasonably priced ;) side, but have not tried
either - I was hoping that someone else has or has experience with
other apps.
