Cannot log into 4.10 machine via ssh

[Peter Ulrich Kruppa]

Hi!

We are using Putty to log into our FreeBSD 4.10 Samba Server for 
administration.

Recently this doesn't work any more:
We can type in our login names, but there won't be any password 
prompt.
Even locally from the server's terminal itself nothing happens.

Everything else (pinging the machine, Samba service) works fine.

What can be done?

Thanks for your answers,

Uli.
