Hello Advensys,
Thanks for your post.
Could you please post a full screenshot of your test result?
This issue may be caused by the following issue:
(1) Does your company use Netscaler?
(2) I suspect this issue may be caused by: Exchange 2003 use the DSProxy process to access information from global catalog servers, 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.
Note: If this registry value does not exist, you may need to manually create it.
Thanks,
Emma Li
