FTP blocked on client but works on Gateway Server

Last Modified: 2013-11-29
When I access FTP sites on my Windows XP Pro SP2 machine I get "Internet Explorer cannot display the web page".  The same problem occurs on different clients and different FTP sites including ftp://ftp.microsoft.com/.  Normal HTTP access is OK.  I ran the network diagnostic program on XP and it reports "FTP (Passive): Error 12031 connecting to ftp.microsoft.com: The connection with the server was reset ".

I'm using a windows server 2003 standard edtion SP2 as a gateway.  It has a broadband router connected to one NIC and the internal network connected to the other.  I have routing and remote access enabled with a static route, and NAT.

Strange thing is I can access FTP sites from my gateway windows server, but not from any clients or other servers.  I've tried disabling virus scan/firewall on my client but it didn't help.

Any suggestions would be gladly received!  Thanks, Peter.
