Error when connecting to remote server

Question

Hi,

I have made an application that makes an automatic move of an uploaded file to an external server using your .net package.

This works fine when I am doing it from an XP pro SP1 box (my developer computer), but it fails when I run the code on my webserver which is running Windows 2000 SP4. Both computers are connected to the internet using the same firewall/router.

Does it matter that I have a Serv-U FTP server on my W2K box?

Here is the error message:

Can you FTP from the command-line on the W2K box to your destination? Having an FTP server on the box should make no difference whatsoever (as long as you aren't connecting to localhost).

Hi,

Yes, I can access ftp from my webserver via Command line FTP. I can both send and receive files from my webserver command line client.

Hi,

I tested as you asked, and as you can see from my previous post, I can connect and operate via command line FTP.

But it still fails when I use your library to connect to the same server using Win 2K server, and it works fine when using Win XP Pro.

Any ideas?

Possibly you are using different versions of the .NET runtime on the two machine?

No, both boxes are running .Net Framework 1.1

I have now stopped using this library and started using XCeed FTP library for .net. Much better documented, and support works. That is wort paying a little for.

We're sorry it didn't work for you. You always have the option of paying for support with our free libraries, but there is a limit to the amount of free time we can dedicate to answering specific questions on the forums. Also, many people find having the source available is extremely useful, and enables them to solve many difficulties themselves.
