Explanation

This Warning event indicates that the Exchange server was unable to contact a global catalog server. If there is another global catalog server in the site, Exchange will use that server. The global catalog server could be unreachable due to network connectivity issues.

User Action

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

Make sure that the global catalog server is running and can be reached.
If you have recently promoted a domain controller to be a global catalog server, restart that global catalog server. You need to restart this server for those changes to take place.
If you are having difficulty resolving the issue, contact Microsoft Product Support. For information about contacting support, visit the Contact Us page of the Microsoft Help and Support Web site.
