How to Resolve Exchange Event ID 1121 and 5000

Microsoft facilitates you to configure Windows Server operating system as a global catalog server. Global catalog is basically a distributed data depository, which comprise of the searchable, partial demonstration of each object in each domain in multi-domain AD DS (Active Directory Domain Services) forest.

It offers enhanced performance over typical Windows Servers. However, you may not start Exchange Server services on the global catalog server and thus the EDB (Exchange Server Database) can not be accessed. It may cause database corruption and lead to data loss. At this point, you are required to go for Exchange Server recovery solutions to extract data from EDB file.

Exchange Server services cannot be started if you Install the Exchange Server 2007 on global catalog server. But, it is possible to start other server related services manually. It may take a very long time to shut down the servers in such configuration. Furthermore, you may encounter the below events in Application Event Log of MS Exchange Server:

Event ID: 1121 
Source: MSExchangeIS 
Category: General 
Type: Error 
Description: Error 0x96e connecting to the Microsoft Active Directory. 

Event ID: 5000 
Source: MSExchangeIS 
Category: General 
Type: Error 
Description: Unable to initialize the Microsoft Exchange Information Store service. - Error 0x96e.
