RE: Cannot access redirected FTP in active mode.

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hi David,

Acorrding to your description, looks like the problem is either on your
private network or firewall setting on those clients but not on the IIS FTP
server. As you know, in FTP active mode, data connection is established
from FTP server(default port is 20) -> client . So this is usually
impacted/blocked by a client side firewall. All the details is documented
in the following article:

Information About the IIS File Transmission Protocol (FTP) Service
http://support.microsoft.com/?id=283679

I'd like to suggest you temporarily shutdown the firewall on the
problematic clients or between server and the private networking to narrow
down the root cause.
