Yes.

FYI, I had to run ssh-host-config as a domain user.  When I first ran it 
as a local Administrator, the ssh-host-config script printed the following:

I tried adding netlogon as a dependency to sshd, but didn't see any 
change in behavior.

Changing it from "Automatic" to "Automatic (delayed start)" fixed the 
issue.  This is my first time messing with Windows services and didn't 
see this option initially.

Thanks for the suggestion Brian!
