Thats what i have written, what do i have wrong?

Black screen for 20 seconds then "No servers could be used"

I got most of my .bat set up i believe but i can't figure my head around the passwords. If i put in nothing or empty it tells me it can't connect, if i don't put in ANY password argument it says invalid credentials. What do i do?
