FTP service running on one NW 6.5 sp8 server (//server6) in the tree.

I have rights to all servers in the tree.
All file servers are Netware 6.5 sp8
My home directory and default ftp directory is //server1/data/home/me.
Within an ftp session I can
cd //server2/data/dept
but when I try
cd //server3/data/dept
I get the message "550 File Server unavailable".

I have a department whose home directories and department share are on //server3 and I need to enable ftp to those areas. The only difference I can think of between Server 2 and Server3 is that server3 also runs AFP - does that get in the way of Netware ftp?

How do I troubleshoot the ftp connection to Server3?
