If I have a Windows server domain - e.g. domain 1 and then I create another domain - domain 2 - and I have users with exactly the same name and password on both domains, is there any way I can have a user in domain 2 log in so that they have access to all the resources the same user name/password would have on domain 1 without using a trust between the two domain? I want them to access mail, folders, printing, etc just as if they had logged in with the same name password on domain 1? Would I need net use commands and if so which ones? If I can do this with different versions of Windows e.g. domain 1 - Windows 2000 and domain 2 Windows 2003, 2008 and 2003, NT4 and 2003, etc? Specifically I would like to do this with Windows NT and Windows 2008 or Windows 2003. Again I want to know if this can be done without trusts.
