Does the user have a valid account and password on the remote system?
If the userid being used is root, does the remote sshd allow direct root logins?
Does using protocol version 1 help (add -1 to the command)?
Does the remote sshd require public-key authentication?
Does the remote sshd require successful reverse DNS lookups?

You might want to run the remote sshd in debug mode, to see if it puts out 
anything interesting:
sshd -e -D -d -d
Since the sysadmin won't want to make it impossible for others to SSH in while 
this is going on, adding an alternate port number will let you test while not 
causing disruption:
sshd -e -D -d -d -p 2022
and then you'll need to modify the sftp command to connect to that port:
sftp -oPort=2022
