I know this has been asked before, but I looked at the other questions and they didn't help, so here goes...

I installed cygwin (only OpenSSH and whatever else it automatically chose for it). I ran the ssh-host-config and entered 'yes' for everything (basically a manual ssh-host-config -y).

It installed the service.

However, everytime the service starts, I get the following in the /var/log/sshd.log:

    158 [unknown (0xED4)] ? 2672 handle_exceptions: Exception: STATUS_ACCESS_VIOLATION

And this goes on for as long as the service is running. I cannot connect to the machine.

However, if I run /usr/sbin/sshd manually, it starts fine, and I can connect to the machine.

The machine:

  • Windows XP Pro
  • Firewall - disabled
  • Account: admin

Stuff I've already tried:

  • Removing everything cygwin and reinstalling (registry keys included)
  • Restarting the computer (multiple times)
  • Installing cygwin in safe mode as suggested here
  • Giving SYSTEM "Full Control" to the Cygwin folders, as suggested here

Any help is greatly appreciated!

Found the problem, in case anyone else has the same issue:

There were two versions of 'cygwin1.dll' on the system. It was looking at the wrong one. If you have this issue, search for the file, and remove one of them (depending on which version you are keeping).
