SYMPTOMS
When a Microsoft Outlook client computer connects to Microsoft Exchange Server 2003, the DSProxy service does not direct the client to the global catalog server that you want to use. Instead, the DSProxy service directs the client to a domain controller that is in a different domain. You do not want to use this domain controller as a global catalog server.
CAUSE
This problem may occur if you installed Microsoft Exchange Server 2003 Service Pack 2 (SP2). The algorithm that is used by Exchange Server 2003 to refer Outlook clients to global catalog servers was changed in Exchange Server 2003 SP2.

MORE INFORMATION
Typically, Exchange Server 2003 servers refer Microsoft Office Outlook 2003, Microsoft Outlook 2002, and Microsoft Outlook 2000 client computers to global catalog servers for directory access. If you are running a version of Exchange Server 2003 that is earlier than Exchange Server 2003 SP2, Outlook client computers are referred to global catalog servers that are located in the same site as the Exchange server on which the users' mailboxes are located.
When a user account is in a different domain than the Exchange server on which the user account's mailbox is located, the Outlook client is referred to the global catalog server in the Exchange server domain. In this scenario, the Outlook client receives only read access to the global catalog server. Therefore, the Outlook user cannot configure a delegate or any public distribution lists that the Outlook user owns.
After you install Exchange Server 2003 SP2, the Exchange server refers Outlook clients to global catalog servers in the user's local domain. Therefore, the issue in which Outlook users receive only read access to the global catalog server is resolved.
In an environment in which many user mailboxes are located on Exchange servers in other domains, you may experience a significant change in the load on the global catalog servers in the users' local domain. This change in load occurs because referrals that were originally targeted to global catalog servers in the Exchange servers' domains are now all targeted to global catalog servers in the users' local domain. Therefore, the global catalog servers in the users' local domain may not be able to handle the additional load that is caused by the Outlook directory search requests.
