You mean after system startup? It tells me that "the requested service has already been started." ... and sshd still fails when I approach it again.

Yes ... as I wrote in the original post "F-Secure" has been installed, and yes, it may be the culprit ...

I did ... as instructed in /usr/share/doc/Cygwin/_autorebase.README - rebase-trigger fullrebase - shut down "Cygwin" (incuding: cygrunsrv -E sshd) - execute setup ... It did not help. But read the error report in the sshd.log again: it is not the "classical dll clash" (description by Michael Lemke :-), it is "something else" (related to the "lockstep" in which parent and child are forced by the cygwin dll when the fork syscall takes places, and yes, in those circumstance a dll clash may occur if the Cygwin dlls have not been properly rebased). As rebasing did not help, I tried some other things, but then decided, it would be far wiser to install the last valid version of Cygwin. However the result was the same ... Subsequently tried the peflags command ... reconfigured openssh in a different way (using cyg_server as the privileged account - although not required in XP) Did some things (that I cannot really remember now). Finally I decided I did not have a clue of what was going on (and of what I was doing). That is why I decided to post my problem. I am clueless. More so, as I can make sshd work by just restarting it ...
