I have one server that has a problem with sshd. And
its a strange problem that I don't know what is
causing it. Seems to be an authentication problem but
I'm not really sure about that. Also there is a
problem starting it.
When I try starting it the server times out on start.
it starts fine though if I start it with the following
command.
/usr/sbin/sshd -d -d -d (while looking for problems)

$ /usr/sbin/sshd -d -d -d

Then when I try to connect I get the following.

Event Viewer shows the following errors

Event
Date:      11/21/2005  Source:     Security
Time:      15:44       Catagory:   Login/Logoff
User:      NT AUTHORITY\SYSTEM
Computer:  MYSVR

Description: 
Logon Failure:
 	Reason:		An unexpected error occurred during logon
 	User Name:	administrator
 	Domain:		ABBATECH
 	Logon Type:	3
 	Logon Process:	Cygwin.1
 	Authentication Package:
MICROSOFT_AUTHENTICATION_PACKAGE_V1_0
 	Workstation Name:	 


When I try logging in it logs in and then immediately
disconnects me.
If I type the wrong password it brings up the prompt
again
If I use key authentication it just immediatly kicks
me out. It looks like its authenticating passwords and
encryption keys.

Here is an attempt without a passkey and with a
password
administrator@mysvr's password:
debug3: Trying to reverse map address 172.24.0.151.
Last login: Fri Nov 18 16:58:44 2005 from 127.0.0.1
debug1: permanently_set_uid: 500/513
setreuid 500: No such process
debug1: do_cleanup
Connection to mysvr closed.

I've been trying to lookup "setreuid cygwin sshd" on
google but have not run into a satisfactory condition.

The error reported in the event log seems to be a
mismatch time with domain server error but I made sure
that the time on the machine is synced with the domain
controller. And if it was a mismatch time I can login
via rdesktop thats how I normally login to this box
and that would fail.

Has anyone else run into this problem? I had no
trouble installing on Windows 2003 or Windows XP.
