It could be that the IP address they are using does not have a proper / 
correct DNS entry - i.e. the IP does not resolve back to a host name or the 
host name it has does not resolve back to that IP.

Check in the /var/log/messages log and see if anything is logged for his 
attempts.

Another thing to look out for is if he uses a FTP proxy / firewall - some 
require you to use "passive" (PASV) mode FTP transfers.

Hope that helps...
