I finally figured out why I was having so much trouble access FTP sites outside my firewall. I could access any site I wanted from DOS but not using the internet transfer controls in VB6. After analyzing what I was entering at the DOS prompt, I figured out how to duplicate that with the Inet control. What I didn't understand at the time was the Inet1.URL needs to = ftp://web."myproxyserver".com. I thought setting the Inet1.Proxy assigned that and the URL property was used to assign the name of the FTP site I wanted to access.

Hopefully, this will help someone else and save them hours of frustration.
