STATUS

Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server.

This problem was first corrected in Microsoft Exchange 2000 Server Service Pack 2.

MORE INFORMATION

When DSaccess is initialized by the system attendant, DSaccess determines which domain DSaccess exists in. When a DN-based read is made through DSaccess, DSaccess checks to determine whether the object that is being read is in the "local domain." If the object is in the local domain, DSaccess sends the request to the Lightweight Directory Access Protocol (LDAP) port (389) of a domain controller in the local domain.

If the server is using a domain controller that is in a child domain (so that the domain controller does not have information about the local domain), that domain controller returns a referral. However, DSaccess cannot support referrals.

In versions of Exchange 2000 that are earlier than Exchange 2000 Server Service Pack 2 (SP2), DSAccess reads all of the domain controllers as though they are in the local domain; therefore, there is no check to determine whether the domain controller is appropriate for the request. In versions of Exchange 2000 that are earlier than Exchange 2000 Server SP2, there is no failover to the global catalog server.

In Exchange 2000 Server SP2 and later, DSAccess uses the global catalog server in this situation, which eliminates the problem entirely.
