IIS 7 FTP - Command line client works, but GUI FTP doesn't?

We just setup an FTP server on IIS 7. Everything works fine from the Windows built in command line FTP. I can login and see and create folders, etc. But logging in with a couple of different GUI FTP programs does not work. Server is behind a SonicWall 2040

Here's a log from WISE-FTP, also tried FileZilla

! Connecting to x.x.x.x...
< 220 Microsoft FTP Service
< 331 Password required for tuser.

    Accepted Solution

    Have you tried to switch Passive mode off in your clients? As far as I see, your problems are because your clients are trying to use passive mode (windows built-in client doesn't) and IIS is not running in passive mode (it could but should be twicked for it, for example, as described here )

    Thanks. I had figured this out on my own since I asked the question. Good info on reconfiguring IIS to go passive.
