Insufficient permissions to write to the configuration data cache - Event 6395 (SharePoint 2010 Products)
Published: May 12, 2010
Alert Name: Insufficient permissions to write to the configuration data cache
Event ID: 6395
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, most 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.
This error indicates that a permissions issue is preventing specific trusted accounts from writing to the %systemdrive%\Users\AllUsers\Microsoft\SharePoint\Config directory.
Symptoms: The following message might appear in the event log: Event ID: 6395 Insufficient permissions to write to the configuration data cache. More information is included below.
Cause: The configuration cache directory has security settings that prevent write access to its contents. Although configuration objects can be updated farm-wide, the objects are not updated locally.
Resolution: Assign sufficient permissions to the configuration data cache
Make sure that the WSS_ADMIN_WPG and WSS_RESTRICTED_WPG local groups have been granted permissions to write to the %systemdrive%\Users\All Users\Microsoft\SharePoint\Config directory. You must have Modify permissions to the directory in order to perform this task.
