Description:

The information store could not be opened. The logon to the Microsoft Exchange Server computer failed.

ID no: 80040111-0286-00000000



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:
 * 1) Bring up another domain controller in the domain.
 * 2) 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.
 * 3) Right-click NTDS Settings, and then click Properties.
 * 4) Click the General tab, and then click to select the Global Catalog check box to assign the server the role of global catalog.
 * 5) Allow sufficient time for the account and schema information to be replicated to the new global catalog server.
 * 6) Restart the server.
 * 7) 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.
 * 8) Right-click NTDS Settings, and then click Properties.
 * 9) Click the General tab, and then click to clear the Global Catalog check box.
 * 10) Restart the Exchange Server 5.5 computer.
