problems with FTP

Hello everyone.  Im experiencing an issue with setting up an FTP server.  This is something I have done many times in the past, but this time things arent going so smoothly for me....

When attempting to connect to my site from a remote location, I receive the following error-

Windows cannot access this folder.  Make sure you typed the file name correctly and that you have permission to access the folder.
Details:
The connection with the server was reset

I have no problem accessing the site locally so I know its not an authentication issue.  My first thought lead me to a firewall or router config.  After banging away with both of them and getting nowhere, I removed them all together.  Right now, this PC is sitting directly connected to the internet with no firewall and no router.  There is also no software installed that does port blocking or any blocking of any sort for that matter.  I have disabled the Windows firewall, given the everyone group full control of the FTP root directory, contacted my internet provider to verify port 21 is not blocked on their end, and tried multiple FTP server applications.

At this point, Im tired, frustrated, and looking for an easy out.  Can anyone help me out?

Thanks a ton!

Oh BTW, this is a WinXP Pro box running SP2
