Product: Exchange
Event ID: 111
Source: MSExchange Search
Version: 8.0
Symbolic Name: NonFatalError
Message: Exchange Search Indexer is trying to recover from a non-fatal error (%1) for more than %2 minutes. It will keep retrying until it succeeds or hits a fatal error.
   
Explanation

This Warning event indicates that the Microsoft Exchange Search service is trying to recover from a non-fatal error. An example of a non-fatal error could be when Exchange Search fails when you are trying to connect to Active Directory (domain controller). If the problem is because of domain controller connectivity issues, Exchange Search will continue to try to connect. When this problem occurs, search in online mode may take a long time to return results for mailboxes on the affected mailbox server. In the event description, the first parameter is the error information and the second parameter indicates how long the Exchange Search service has been trying to recover.

   
User Action

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

  • Run the Best Practices Analyzer tool under Toolbox in the Exchange Management Console of the Exchange Server. Running the tool will help identify other possible causes.

  • Use the nltest /dsgetdc: domainname command at command prompt to verify that a domain controller can be located for a specific domain.

  • Use the NSLookup tool to verify that DNS entries are registered correctly in DNS. Verify that the server host records and GUID SRV records can be resolved. For example, to verify record registration, use the following commands:

    nslookup servername . childofrootdomain . rootdomain .comnslookup guid._msdcs. rootdomain .com

  • To detect domain controller problems, run the DCdiag utility at a command prompt. The utility runs several tests to verify that a domain controller is running correctly. Use this command to send the results to a text file: dcdiag /v >dcdiag.txt

  • Check the Application event log for related events.

  • Get additional help by posting the issue at Newsgroups: Exchange Server and Outlook.

  • If the problem persists, contact Microsoft Product Support Services. For more information, visit the Contact Us page of the Microsoft Help and Support Web site.
