Is there a 'A' record in DNS for server A as well as a reverse lookup entry? What happens if you try to ssh by IP address or put the IP address in your /etc/hosts file on B? Is there a software firewall on A that does not allow ssh connections? I'm assuming of course that you already have an ssh server up and running on A. P.S. Sorry for the top posting.
