ssh: connection closed by remote host

Hola, list ...

after once again scanning hte mailing list archives, the web,
the documentation, some books and other stuff, I am still helpless
on this one.

Attached are two snippets of my unsuccessful attempts to connect
to sshd.

On the client side I always get "connection closed by remote host"
and after trying the whole weekend on this, I really give up ...

Any help would really be appreciated.

PD: Software version is current. OS is W2K on both sides, daemon
    sits on a "hardened" W2K server in our extranet.

Any technology distinguishable from magic is insufficiently advanced.
