After you apply Microsoft Exchange Server 2003 Service Pack 1 (SP1), Outlook clients that use remote procedure call (RPC) over HTTP connections to a server that is running Exchange will use the DSProxy process to access information from global catalog servers. Therefore, if you view server connections in the Exchange Server Connection Status dialog box in the Outlook client, you will see the Exchange computer listed in the Server Name column for the item where the Type column lists Directory. These changes are intentionally made by Exchange 2003 SP1 so that global catalog servers no longer have to be published through the RPC Proxy server.

To override this new behavior, create and set the following registry value on your back-end server that is running Exchange 2003. If this registry value is set, the RFR Service behavior will revert to the pre-SP1 method of returning a global catalog to the referral interface.
To create and to set the registry value, follow these steps:1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MsExchangeSA\Parameters
3. Right-click Parameters, click New, and then click DWORD Value.
New Value #1 is selected.
4. To rename this value, type Do Not Refer HTTP to DSProxy, and then press ENTER.
5. Double-click Do Not Refer HTTP to DSProxy, and then type a value other than zero (0) in the Value box. For example, type 1 in the Value box.
