Yes, use -e on the command line to sshd. e.g., 

cygrunsrv -I sshd -p /usr/sbin/sshd.exe -a "-D -e"

This will throw all the logging into /var/log/sshd.log

I've had the same problem; I've determined that it only fails with versions
later than 1.3.10-1.  Are you running the same version of Cygwin on your other
box?
