HTTP 404 Not Found Wss SHAREPOINT 2007 2010 errors web.config Central Administration website

When you try to browse a Central Administration website or a SharePoint website, you may receive the following error message:

HTTP 404 Not Found

Or, the following message is logged in the Application log:
Event Type: Error Event
Source: Windows SharePoint Services 3
Event Category: Topology
Event ID: 6800
Description: The database WSS_Content on ComputerName \Microsoft##SSEE is not accessible to missing Windows Internal Database signatures.

This problem may occur when you install a patch manually or through Windows Update. If another service has connected to the Windows Internal Database prior to the upgrade, SharePoint cannot make a connection, and the upgrade fails. This puts the farm into an inconsistent state that must be resolved by a successful upgrade operation.

To resolve this problem, follow these steps to restart the SharePoint services and to complete upgrade:

1 Click Start, click Run, type cmd, and then click OK.


2 Locate the following folder:
%COMMONPROGRAMFILES%\Microsoft Shared\Web server extensions\12\BIN

3 At a command prompt, type the following command, and then press ENTER:
psconfig -cmd upgrade -inplace b2b -wait –force


4 If the upgrade does not complete succussfully, type the following commands at

the command prompt, and press ENTER after each command:


net stop MSSQL$MICROSOFT##SSEE


net start MSSQL$MICROSOFT##SSEE


psconfig -cmd upgrade -inplace b2b -wait -force
