Go to Run - > Cmd

In the DOS box, ping abc - does that work.

If that works, then try ftp abc and see if that works or not.

Check your firewall if you have any running on he machine and see if FTP ports 21&22 are blocked or not.

If there is a firewall between your machine and the UNIX machine (abc) and if FTP is blocked by that firewall, then talk to your network admin.

First check the ping to the ftp box.

Then try to nslookup ftp box.

Start ---> Run ---> cmd

ping <Server Name>

nslookup <Server Name>

If both works then try to execute below given command.

telnet <server name> 21

If you get escape character then everything works file.

If nothing works, Please show us the output of above given commands.

Can you ftp to its IP Address : 10.67.6.134  (from your ping above).

My guess, based on the telnet not working, is ftp is not setup on the linux box.  you can try to scp (its like ftp but via ssh).  A free program is winscp

Or have a look on the linux box and ensure ftp is setup.

I am thinking that either ftp is not running on the linux box or the linux box as iptables running blocking ftp traffic.

Differnet versions and flavors of linux have differnet ftp deamons so a little hard to say how to check if ftp is running.  You could check your services and see if there is an ftp of some sort in the list.

on fedora you can type setup, then select services and scroll down.

for the iptables check
iptables -L -v
should show all the main rules and tables.
