Someone else had a similar problem a few weeks ago.  I had a similar 
problem several months ago.  My problem turned out to be a 
configuration issue on a Checkpoint firewall.  Here's what our network 
administrator said:

	Ok, if they are running Checkpoint FW-1, try comment out the following line in
	$FWDIR/lib/base.def and reinstall the policy:

	#define FTP_ENFORCE_NL

Let me know if it works.
