IIS 7 / Windows 2008 has connectivity problems with remote client

blueskybooking used Ask the Experts™
I am able to connect and use "ls" from the local machine and another remote machine.

On my computer though, I am able to login, but not able to display "ls".

Earlier, I got an error message like this:
500 'POPORT 192,168,1,1,19,138' Command not understood

I was able to determine it was with my router, so I have bypassed it now by connecting directly with my cable modem.

It doesn't give that error, but now it just hangs after executing the "ls" command.  There are several directories and it doesn't come back to the ftp> line.
C:\>ftp xx.xx.xx.xx
Connected to xx.xx.xx.xx.

Are you using the new FTP 7.5 for IIS 7?

If so have you configured the Passive Port Range for the FTP Service? And have you configured the Windows Firewall to let FTP traffic through?

Windows Server 2008 contains a built-in firewall service to help secure your server from network threats. If you choose to use the built-in Windows Firewall, you will need to configure your settings so that FTP traffic can pass through the firewall.

Have a look at the following website

Configuring FTP Firewall Settings


I have removed my router (client side) from the mix which seems to have resolved the problem.  I also made a couple of other changes (Anti-Virus/Spyware), so I'm not 100% sure that was it, but it seems to be the best guess.  Thank you for your assistance.
