We have a roblem with a WSS setup on a 2008 R2 server. It is very simple install with 1 site and default settings. Recently users have complained they cannot access the site and they are prompted to enter credentials when browsing to it. I am also unable to access the administration site. Event ID 27745 is repeatedly appearing in the application log but no other logs obviously relating to SharePoint or the SQL instance. Log Name: Application Source: Windows SharePoint Services 3 Date: 14/06/2011 10:14:45 Event ID: 27745 Task Category: General Level: Error Keywords: Classic User: N/A Computer: <fqdn of server> Description: The description for Event ID 27745 from source Windows SharePoint Services 3 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: #50071: Unable to connect to the database SharePoint_Config_be3cf75e-7950-4fa5-a5f5-17a94951cc7f on <Servername>\Microsoft##SSEE.

Hi, According to your description, I guess your database SharePoint_Config had a large file, you need to truncate this and then run a windows SharePoint Timer Service restart. Please have a try. Best Regards David Hu
