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

My experience with Bitvise has been very good.  Especially if you need a
solution that will integrate with Microsoft AD.  Reasonably priced (as
you've pointed out) and reliable.

Hi Folk,

So far as I can tell MS recommends webdav as a secure alternative to
FTP for allowing access to files under windows.  We have found that
MS's implementation of webdav does not perform well with large files
across a wide area networks.  It opens lots of  tcp session that are
so short that the window stuff never gets a chance to optimise
resulting in very slow transfer rates.  We were transferring large MRI
images ( multi GB) between our Medical School and US institutions.
Interestingly we collect the MRI same images from hospitals around the
world with a UNIX based server with out issues but when our users
tried to use the webdav direct between two windows machines the
transfers slowed to a trickle.  After hours of peering at wireshark
traces  we decided that it was a TCP window problem cause my the MS
server chopping the file in to tiny pieces and sending each over a
different TCP session.

I am looking for an SSH 2 based system (free preferred ;) or
commercial) that we can recommend to any of our users who need to
transfer files between windows systems.  I know several such systems
exist and I'm hoping someone has already done the leg work of
evaluating them... I'd be happy to have one free one and a commercial
offering to recommend.

Thanks, Russell
