The problem is, if you're in a session, there are two sshd processes 
running:


Gerrit AT ISMENE ~
$ ssh ismene
Enter passphrase for key '/home/Gerrit/.ssh/id_rsa': 
Last login: Mon Jul 30 09:05:44 2001 from ismene.192.168.5.5
Fanfare!!!
You are successfully logged in to this server!!!

Gerrit AT ISMENE ~
$ ps -e
      259     221     259        254    3 11002 16:11:39 /usr/bin/ssh
      258       1     116        258    ?   18 16:11:40 /usr/sbin/sshd
      146     279     279        137    ?   18 16:13:48 /usr/sbin/sshd


BUT, you can see at the time row how long each process is running
and so you know what the parent is.

If you do '$ cygrunsrv -E sshd' your session will be stopped and 
you are still logged in at the child sshd.

$ cygrunsrv -E sshd
$ ps -e | grep ssh 
      259     221     259        254    3 11002 16:11:39 /usr/bin/ssh
      258       1     116        258    ?   18 16:11:40 /usr/sbin/sshd


Then you may change whatever is needed and restart the *service*

$ cygrunsrv -S sshd
$ ps -e | grep ssh
      259     221     259        254    3 11002 16:11:39 /usr/bin/ssh
      258       1     116        258    ?   18 16:11:40 /usr/sbin/sshd
      223     115     115        253    ?   18 16:16:16 /usr/sbin/sshd

I hope it works, but i am not in the position to give a guarantee for that:-)
