Damba,

Since your subscription expired, I would suggest that you try downloading Demo version, just to check if the issue was resolved. If that works, you can choose to extend your subscription (we still allow that, but it has to be extended from the date of expiry. Also, price per year is 20 of the component).

Based on my records, I think my subscription expired Sep 8 2008, so 13 months ago. Do you still allow a renewal? For 40 of the current price?

Also, in order to distribute demo version, you will need to install the component on your customers machine, since Demo cannot be distributed (as a trial version limit).

So what is the recommended way to do this? Have them download and install the demo and rename the current DLL in my application folder so it does not find it first? My installer puts your DLL in the same folder as my application.

Does the demo installer put the DLL in a path where the system would locate it universally? EG WindowsSystem32

These users will need hand holding, so I want to be sure I know what to talk them through.

As for the error you are receiving, this error is usually thrown when wrong protocol is used (i.e. using SFTP to connect to FTPS server).

You could also try changing between Active/Passive mode? Also, does setting StrictHost property to true help?

Yet I know the protocol is right -- the code hasn't changed in a long time, and with repeated attempts it eventually works. That is why my first guess was a partial firewall block on the data port range. That could explain a hit or miss success rate depending on the port assigned.

I have always used passive and StrictHost -- it was the only way I could get things to work at all. But other than these recent failures -- mostly from one location -- it has worked consistently.

My user interface currently does not expose those options -- it runs all the transfers automagically when the user clicks a single button. But I guess I can alter the UI to expose them for testing or something if you think it could help. However, with firewalls in the way I would expect passive and stricthost will both be required.
