Hi Julio,

The steps to reproduce have been done directly after installing Cygwin
without any modifications. The logfile /var/log/sshd.log is empty even after
the error has been printed on the Linux machine from which I connected to
the Windows / Cygwin machine.

I executed the commands

$ cygrunsrv -E sshd
$ /usr/sbin/sshd -ddde

using my account (not by the SYSTEM account) and afterwards I connected from
my Linux machine to the Windows / Cygwin machine without any problems! Like
you assumed the problem didn't show up in this mode. When executing
/usr/sbin/sshd using my account everything works fine but when executing it
as service the error occurs.

Michael
