CAUSE

This issue might occur in a mixed Exchange 2000 and Microsoft Exchange Server version 5.5 environment if the Exchange Server 5.5 computer runs on a global catalog server.

NOTE: Microsoft does not support running Exchange Server version 5.5 on a global catalog server because port conflicts occur between the Exchange Server 5.5 directory service and the Name Service Provider Interface.

RESOLUTION

To resolve this issue, designate another domain controller as a global catalog server and prevent the server that is running Exchange Server 5.5 from acting as a global catalog server:

Bring up another domain controller in the domain.
Start the Active Directory Sites and Services Microsoft Management Console (MMC) snap-in, expand the Sites object, and then expand the site_name object. Expand the Servers object, expand the server_name object, and then click NTDS Settings.
Right-click NTDS Settings, and then click Properties.
Click the General tab, and then click to select the Global Catalog check box to assign the server the role of global catalog.
Allow sufficient time for the account and schema information to be replicated to the new global catalog server.
Restart the server.
On the computer that is running Exchange Server 5.5 (that is a global catalog server), start the Active Directory Sites and Services MMC snap-in, expand the Sites object, and then expand the site_name object. Expand the Servers object, expand the server_name, and then click NTDS Settings.
Right-click NTDS Settings, and then click Properties.
Click the General tab, and then click to clear the Global Catalog check box.
Restart the Exchange Server 5.5 computer.
