SSHD privilege separation and Cygwin!

So … I’ve had Cygwin running on my computer for a while, but I recently moved it from one hard drive to another (since I decided that keeping it on an external USB drive was a fairly dumb thing to do). And now, when I try to start the sshd service when I have privilege separation enabled via a “sshd” user, I get a “System error 5/permission denied” error.

But wait, there’s more! Because I made a really stupid mistake with “chmod” which caused me not to have permission to run any programs at all, I had to reinstall Cygwin altogether. Now, when I try to start the sshd service, it fails, and adds “The service did not report an error.”

Thing is, when I turn off privilege separation, it works fine. I have a feeling that it’s something to do with the dummy “sshd” user. Any help?
