We are running an SBS 2008 server with WSS 3.0 for our SharePoint site. Some updates were applied last night, and this morning I am getting a "Cannot connect to the configuration database." when trying to access the site.
The updates were a bunch of .NET Framework 4 Client Profile and Extended updates, and one Security Update for WSS 3.0 (KB 2493987)
I was trying to back the updates out to at least get SharePoint functioning again, but the WSS update does not allow me to uninstall it from the "Installed Updates" screen. I can removed the .NET updates though.
So, 2 questions: 1) does anyone know why I would suddenly be unable to connect to the configuration database from these updates, and 2) why does the uninstall option not come up on the WSS update item?
