Files Sent to Web Host End up as 0 Byte Files

Specs: Windows 7, P4 2.66Ghz/3gb RAM
I am having problems uploading files to one particular host that I use via FTP clients. Every file I send to that host always ends up as a zero byte file. I can upload files to other hosts with no problems.

However, I tested logging into the host using the ftp command in the Windows Command Prompt and using the "put" command. When I do that, the files transfer successfully. Same if I enter the ftp address in the Windows Explorer address bar and use Windows Explorer to transfer the files.

But if I try FTP client software (RhinoSoft FTP Voyager, FireFTP plugin for Firefox, and Filezilla), the end result is a 0 byte file on the remote server. The 0 byte file problem is just for that one host. In contrast, I can transfer files to other hosts successfully using the above clients both with U-verse at home and at also from work via my employer's network.

Does the fact that the files transfer correctly via the Windows command prompt or Windows Explorer, but transfer as 0 byte files via the ftp clients offer any clues as to what might be wrong?

The administrator of the host server that is giving me problems says he can log-in to an FTP client with my ID and password and upload files with no problems. He asked someonel else to try and they could, too. I don't understand how he is able to successfully transfer files where I have tried multiple FTP clients on 3 different PCs on two different networks, and I cannot transfer a file without it being reduced to 0 bytes.

Thanks in advance for any ideas on this.

Are the client computers, you tried to upload files with, behind any kind of firewall?
And have you checked the firewall logs for any blocked packets, corresponding to the FTP connection. I think it must something at the end of any uploaded file.

What's about downloading files with the client software.
Are the files correctly stored to your computer?

Yes, I am behind firewalls, but they do not block any of the other servers taht I upload to via FTP. Also, they are set to permit FTP communication.

I am able to download, and the files download with no problem. It's the upload where they upload as a 0 byte file.

Ok, what's about a test?
When you upload a file via FTP client to that server, and then download the just uploaded file, what is the file size of the downloaded file?

If I upload a file that becomes 0 bytes on the server, then download it back to my PC, the downloaded file is 0 bytes.

Hmm, so where is the difference between this one server, where it doesn't work and the other server, where it works properly?

Any proxy between your machine and the server?

Ah, something else. Did you use a personal firewall on your computers, where FTP client upload doesn't work?

Just to clarify, it's not just one server that works, it is multiple servers that work and one that does not.

No proxies in use. I turned off my personal firewall, and checked the U-verse router to be sure that it allows ftp traffic.

Would I be wroing in assuming the software running the host server is the problem, since it is the only server with which I have this issue?

Also would

Yes, you have to check the server side.
Firewall, proxy or whatever.
Also, what FTP server software is running there and does the FTP server software differ from the other server, where everthing is working properly.
