Here's a description of active ftp vs passive ftp:

Active FTP vs. Passive FTP, a Definitive Explanation

In active mode the server needs to connect back to the client so the client firewall must allow that. If anyone has tweaked the firewall settings (you could compare the good machine to the bad machine) then that could do it. Hence my suggestion to try switching off that machines firewall.

In passive mode the client makes both stage connections so the firewall on the client won't be involved. Hence my suggestion to try switching into passive mode by the Windows client requesting 'quote pasv'.

As you can tell I'm saying that it looks like a problem on that client if you are sure nothing on the network has changed.

Okay, I did the passive command and it still does the same, the Firewall setting are the same on all computers, nothing has changed on these.

Did you actually try turning off the Windows firewall on that client?

Can other clients 'get' this same file from the Unix box? (Is there something wrong with that specific file?)

If you have access to the Unix box trying pinging that client from it to prove the Unix box can actually reach that client.

Oh, and temporarily turn off the Anti-virus as well!!! Has the AV setup on this box changed recently?

This reasoning, alas, proves nothing. Windoze network drives and other services (which, in network terms, are RFC1001/RFC1002 services - NetBIOS over TCP/IP) operate on different ports than native TCP/IP services like FTP.

Better check back with the network group and make sure they really have changed nothing.

I hope this helps.

The only thing that changed was the Anti Virus on all the clients, but the same goes for the ones that do work as well. I cant turn off the firewall even when I log on as admin (I am the network administrator!). I tried it with AV disabled and it did the same thing.

How do I ping from the UNIX box back to a Win7 client?

Okay, I can ping back from UNIX to client "connection is alive".

I have accessed the same target file from my client and it works.

The same way you ping any other IP host:

Code:

ping <IP-address>

Replace "<IP-address>" with the corresponding DNS-(NIS-, ...) name if you want to make sure name resolution works from the machine originating the ping.

I hope this helps.
