Not possible for it to "join" the domain. Period. Best you can do on the home machine is to set it's workgroup name to the domains name at which point you shoudl at leats be able to see the other computers. If the server and other computers are shared and have the permissions set to no-password guest access it might be able to access those shares. Even if they have a password though the home box should be able to connect using a valid domain credential in the form of "domain\user" with the password.
