As long as your machines which are not on the domain are using the same DNS servers for name resolution you will be able to find all your domain machines. When you try to open the file share for the machines which are on the domain you will be prompted for a username and password. Enter your domain name and username in the format DOMAINNAMEUserName and your password in the correct boxes and click OK. If the account which you enter has access to the machine you'll be shown the data within the network share. If not, you'll be given an error message saying that you don't have access to the folder.
