Key Exchange Failed (error message)

I am running the SSH Secure Shell (TM) client and trying to connect to my Solaris 9 box (Which runs Sun_ssh_1.0) and I get the message

         'Server responded "Key Exchange Failed.". Key exchange with the remote host failed. This can happen for example if the remote computer does not support the selected algorithms.'

When I use PuTTY, I have no problems.

Any thoughts?
