I am running a VNC onto the server, and using a window in there can

My only thought is that a few days ago I changed the hostname using
system-network-config but I am pretty certain that I could still ssh
in after doing that. It just stopped working this morning.
I've even tried rebooting in case there were odd processes hanging
about, but that's made no difference. At the moment I'm totally
stuck!
Try a different tack. Get a root shell on the machine in question and
fire up sshd in no-fork mode under strace:
strace -o /tmp/ssh.trace sshd -D -p 2222
Then try to ssh into that machine on port 2222 (or whatever you
choose). Assuming it fails, close down the temporary sshd and point
$PAGER at /tmp/ssh.trace. The failure point will likely be about 90%
of the way through the file. (The end of the file will be related to
closing down sshd).
