Re: Cannot Connect to FTP Server

I would either: On the Exceptions tab, see if you can enable the program
rather than any specific ports. Or, go to the Advanced page and turn on
logging. See what it reports when you have a failed connection attempt with
21 open.

If I disable the Windows firewall, all is OK. If I enable the firewall
and allow TCP port 21 in Exceptions it's not. Is port 20 also required?

Can this be the Windows Firewall on the XP Pro box (the one hosting the
FTP server)?

SBS2003 SP1 Premium (ISA 2004 SP2), Windows XP Pro SP2. I have set up a
test FTP server (Globalscape Secure FTP Server) on a workstation on the
same LAN as the SBS server. Eventually I will move it to a DMZ and allow
internet access. The site is running OK and I can logon to it locally
and create folders, etc. What I can't do is log on from any other PC on
the LAN no matter what I have tried:

1. Local login to PC (also domain login)
2. Disable ISA Firewall client
3. Turn off IE proxy settings

No matter how I try to connect, I get the following:

1. ftp using IE: no login prompt appears and connection just times out
with "server has reset the connection"
2. Command line ftp: no login prompt and then eventually I get
"connection closed by remote host"

I thought it might have something to do with ISA but I have disabled the
proxy and the firewall client and it makes no difference. No matter
what, there is never any port 21 activity in ISA monitor.

I can connect to the FTP PC fileshares from any PC on the LAN.

This is the second FTP server (Titan FTP) I have tried with the same
result.

Can someone please help me with this?
