Dealing with an installation of SharePoint Foundation 2010 (14.0.7143.5000) that was included with Small Business Server 2011.
Everything worked fine yesterday, until the latest cumulative update (KB2910904) was successfully installed overnight by Windows Update. Now, all SharePoint sites and pages come back with the error below.
I tried running
psconfig -cmd upgrade -inplace b2b -wait, which completed successfully but didn't fix the problem. (EDIT: doing that took down Central Administration as well)
As a test, I also tried restoring the pre-update web.config files, but that did nothing.
The Windows logs are equally unhelpful, logging one warning (1310) whenever I try to load a page in my browser.
Server Error in '/' Application.

UPDATE: I tried resetting the farm account password, but still no dice. I was able to log in with SQL Server Management Studio as the farm account, but I still get blood in the logs (3760). This guy was having the same issue as me, but didn't get anywhere either.
