Product: Exchange
Event ID: 1053
Source: MSExchange Extensibility
Version: 8.0
Symbolic Name: MExAgentInstanceCreationFailure
Message: Agent ‘%1’ failed to create an agent instance with error ‘%2’.

This Error event indicates that the agent specified in the event description could not initialize because of a Microsoft Exchange-specific exception. The event description indicates the exception that caused the problem.

This error may be logged if the resources that the agent requires are not available. For example, if the agent cannot connect to the Active Directory directory service, this error may be logged. It may also be logged for other reasons when attempts to create an agent instance fail.

User Action

To resolve this error, do one or more of the following:

  • Review the exception that is specified in the event description to better understand the cause of the problem. To search for more information about the specific exception, visit the Search the Support Knowledge Base (KB) Web page and the Exchange Server Community Web site.

  • If you suspect an Active Directory resource issue, run the Dcdiag command-line tool to test the health of the domain controller. To do this, run dcdiag /s:<Domain Controller Name> at a command prompt on the Exchange server. Use the output of Dcdiag to determine the cause of any failures or warnings that are reported. For more information, see Dcdiag Overview at the Microsoft Windows Server TechCenter.

  • Troubleshoot network connectivity issues. Use the Ping or PathPing command-line tools to test basic connectivity. Use Ping to isolate network hardware problems and incompatible configurations. Use PathPing to detect packet loss over multiple-hop trips. For more information, see Microsoft Knowledge Base article 325487, How to troubleshoot network connectivity problems.

If this event still occurs after you try to resolve this issue, do one or more of the following:

  • Contact Microsoft Product Support. For more information about how to contact support, visit the Contact Us page of the Microsoft Help and Support Web site.

  • Disable the agent that is specified in the event description. However, if you disable the agent, you disable the functionality that is provided by the agent. For information about how to disable a transport agent, see Disable-Transport Agent.
