rem DESCRIPTION:
rem This script reconfigures the Cygwin sshd service. It regenerates the
rem computer's SSH host keys. This is necessary when Sysprep is run and
rem new SIDs are generated.  This script MUST be run by the root account
rem or else the sshd service will not start.

set /A STATUS=0

rem Get the name of this batch file and the directory it is running from
set SCRIPT_NAME=%~n0
set SCRIPT_FILENAME=%~nx0
set SCRIPT_DIR=%~dp0
rem Remove trailing slash from SCRIPT_DIR
