Ahh, we had an issue where once the user logged in hamachi would open but not connect to the vpn (which made remote work impractical). All the batch file does is instigate that connection from the backend of hamachi on startup (as a startup item). Getting the computer to execute a batch file before user login is it a bit beyond my expertise. As to the network ID have you tried user the network name as the ID? You may need to add some syntax if it is not a single word but there must be an identifier that hamachi uses when it logs in.
