Alternate access mapping update failed - Event 6397 (SharePoint 2010 Products)
Applies to: SharePoint Server 2010, SharePoint Foundation 2010
Alert Name: Alternate access mapping update failed
Event ID: 6397
Summary: Several features of Microsoft SharePoint Foundation 2010 rely on scheduled background processes called timer jobs. Administrators can configure and schedule timer jobs by using SharePoint Central Administration. When you use the Services on Server page of the SharePoint Central Administration Web site to start or stop a service, a timer job performs this action.
To improve the performance of SharePoint Foundation 2010, much of the data in the configuration database in SQL Server 2008 is kept in a local file-system cache, called the configuration data cache. SharePoint Foundation 2010 uses the timer service to keep this cache synchronized with the configuration database. Alternate access mapping is a feature of Microsoft SharePoint Foundation 2010 for administrators to configure a load-balanced system by mapping an incoming URL to alternate URLs that are used by SharePoint Foundation.
This error occurs when the timer job that is used to update alternate access mappings failed on the specified server.

The alternate access mapping settings for Web applications on the local server might not be current.
