echo.
echo server running in background, can close window.
echo can check task manager if server process running.

pause

thank reading.

the "file not found" error coming before echo 'starting server ...' line.  guess is not finding serverconfig.xml file in previous line.  did not specify directory location looking in connected directory.

the 'input redirection' error coming on timeout statement.  don't know why won't accept > nul, try without see if runs.
