Last night, I installed several updates on a SBS 2008 server:
KB2724197
KB2687442 (Security Update to Sharepoint 3.0 SP2)
KB2731847
KB2756822
KB2749655
KB2756497
KB2661254
KB890830
Upon restarting, browsing to http://companyweb resulted in the error:
Cannot connect to the configuration database
I've received this error on other servers before, so I ensured all services were properly running before opening an elevated command prompt and typing:
"C:\Program Files\Common Files\Microsoft Shared\Web server extensions\12\BIN\psconfig" -cmd upgrade -inplace b2b -force
The first 2 of 4 stages succeeded, but then the 3rd failed with the error:
An exception of type Microsoft.SharePoint.PostSetupConfiguration.PostSetupConfigurationTaskException was thrown. Additional exception information: The upgrade command is invalid or a failure has been encountered.
Now browsing to companyweb throws a 404 error. I've tried restarting the Windows Internal Database service, SP search service, none of which help. I am able to access the Sharepoint Central Admin page. Permissions all seem fine, but I may need help confirming this. Can anybody help?
