Considerations for hosting namespaces on servers running a mix of Windows Server 2003 and Windows 2000 Server
Applies To: Windows Server 2003 R2
It is possible to host namespaces on domain controllers and member servers running a mix of Windows 2000 Server, Windows Server 2003 R2, and Windows Server 2003 without Service Pack 1 (SP1), but some functionality is disabled or available inconsistently, depending on the operating systems on the servers. Some examples of mixed-mode behavior are as follows:
If domain controllers or namespace servers are running Windows Server 2003 without SP1 or without Windows Server 2003 R2, they cannot provide referrals that support target priority or client failback.
If domain controllers or namespace servers are running Windows 2000 Server, they cannot provide referrals that support target server priority or client failback; nor can they order targets by lowest cost in referrals. Additional configuration is required to enable these namespace servers and domain controllers to detect the site of each target server in the namespace. For details, see Update the static site table on namespace servers running Windows 2000 Server.
If the DFS Management snap-in connects to a namespace server that is not running Windows Server 2003 with SP1 or R2 versions of Windows Server 2003, none of the new configuration settings (such as client failback or target priority) can be enabled. Renaming or moving namespace folders will not work, and delegation will not be effective.
