How DS Referral Is Used
Outlook 2000 clients have added functionality over the legacy MAPI clients because Directory Server information can be stored in the messaging profile. This feature is especially useful when Exchange 2000 is not running on a GC server. A process known as DS Referral has the capability to update the Outlook 2000 client's MAPI profile with an appropriate GC server.
For the first request, the Outlook 2000 client will still go through the DSProxy process. This is because the version of Exchange Server being used on the back end can only be determined upon the loading of emsmbd32.dll, which follows emsabp32.dll. After the first Outlook 2000 client request through DSProxy, the client software will receive referral information that will allow it to directly contact the GC server for future directory requests.
