Hello there. Bob Drake here to discuss how Windows Server 2008 “Read Only Domain Controllers” (RODC’s) authenticate users differently from the way Windows Server 2003 and Windows Server 2008 standard domain controllers do. The “Read Only Domain Controller” is new to Windows Server 2008 and allows for the installation of a domain controller to accommodate common scenarios where users are authenticating over a wide area network (WAN) or there is a physical security concern for the domain controller, such as installations at branch office locations. Another new feature to Windows Server 2008 RODC’s is “Password Replication Policy” and depending on how they are configured determines how an RODC authenticates a user.
