Thanks, Corinna, for asking if sshd was called with the -D option. This 
was the point, although I do not really know why -D was missing (I used 
ssh-host-config).

This is was came out before (sshd in fact was running):

$ cygrunsrv -Q sshd
Service             : sshd
Display name        : CYGWIN sshd
Current State       : Stopped
Command             : /usr/sbin/sshd

Then I removed the service:

$ sc delete sshd
[SC] DeleteService SUCCESS

Then I rerun the installation script (only selected the service 
re-install, of course using the cyg_server account for Win2k3):

$ ssh-host-config
...
*** Info: Host configuration finished. Have fun!
$ cygrunsrv -S sshd
$ cygrunsrv -Q sshd
Service             : sshd
Display name        : CYGWIN sshd
Current State       : Running
Controls Accepted   : Stop
Command             : /usr/sbin/sshd -D

I guess, when I was installing the service before, I may have changed 
something in the Properties menu of the CYGWIN sshd service, perhaps I 
tested something under the SYSTEM account and then have reverted to the 
cyg_server account, so by this action finally the -D may got lost for the 
call of sshd. BTW, I do not actually understand the meaning of -D (When 
this option is specified, sshd will not detach and does not become a 
daemon. This allows easy monitoring of sshd.)

Thank you again - Ulf-Dietrich
