I've noticed that it is in consistent in that the same code will produce different results depending on the computer is is being run from. On my machine I have no problem establishing a connection to the remote server. When I run my code from my production server I get the above error. Any help would be greatly appreciated.

Thanks,
Justin

It should also be said that I am doing this using the SFTP protocol and the .Net assembly version 5.0.6.

This url does not work.
I got the same problem - would really appreciate help on this one.

The error is because temp folder is filled with tmp files created by Winscp.
Remove these and it will work.
(On a MS Server 2008, the files were create here: C:\Users\<useraccount>\AppData\Local\Temp

You need to login to access it.
Anyway, upgrade to 5.0.7 beta.
