I have an external hard drive and on it are folders with permissions set from a Windows Server 2003 computer. Only administrators have access to this folder. If I use this hard drive on a different Windows Server 2003 computer, the administrator of that computer can't access this folder, even though the administrator has the same password as the original computer that I used to set the permissions. How can I allow access for the administrator of the other computer? Can I give the administrator of the other computer the same unique identifier as the administrator of the original computer?
