Dos Net command?

Alright, had an old boot disk that booted up into DOS and logged a machine onto the network so I could ghost the image. Problem is I've changed the Password of the account I'm using on the domain, and even though I reflected the changes in the batch file it's giving me an illegal password error. I'm pretty sure the password is probably stored somehow in the Net command files on the floppy, anyone know the command to purge any settings (including mapped drives) on the net command?
