I managed to solve this problem, but I'd love some confirmation that I
solved it the right way.
After updating cygwin and rebooting, all of a sudden I couldn't ssh
into my windows box. The remote gave the usual "connection closed by
<bla> port 22" before anything happened. Running in debug mode from
an admin shell didn't yield anything, but looking in the windows
application logs, I saw:
sshd: PID 2588: fatal: seteuid 1056480: No such device or address
The google suggested that the error was pty related, but it was not.
By accident, I noticed that I could log in from an account that I
hadn't set up public key auth, using my password. So I forced ssh to
prompt for my password and viola! I got in just fine.
On the server, I started another admin shell and did `passwd -R
my.username` and input my password. That was the key. I can now log
in using public key auth as I could a few hours ago.
Was that the correct solution? Is that expected? This windows box is
on a domain, so that might have something to do with it.
