Exchange services cannot be started, and event ID 7024 is logged after you install Symantec Mail Security on a Windows Server 2008-based computer that is running Exchange Server 2007

After you install Symantec Mail Security on a Windows Server 2008-based computer that is running Microsoft Exchange Server 2007, Exchange services cannot be started. Additionally, the Exchange Active Directory Topology Service fails, and the following event error is logged in the System log:

Log Name: System
Source: Service Control Manager
Event ID: 7024
Task Category: None
Level: Error
Keywords: Classic
Description:
The Microsoft Exchange Active Directory Topology Service service terminated with service-specific error 2147942414 (0x8007000E).

Note When this issue occurs, you cannot resolve this issue by uninstalling Symantec Mail Security. You may also notice that you cannot clear the Application log events.

This issue occurs because Symantec Mail Security modifies the following registry subkey to write event logs only for Symantec applications:Therefore, when Exchange services tries to log events in the event log, Exchange services receives an "access denied" error message, and Exchange services cannot be started.

To resolve this issue, upgrade to Symantec Mail Security for Microsoft Exchange version 6.06. This version of Symantec Mail Security for Microsoft Exchange includes full support for Windows 2008.
