TFS 2010 restored database, TfsJobAgent cannot connect to database

Question

I have a Team Foundation Server 2010 setup, in which I have TFS on one server and the databases on another. Recently the server with the databases completely crashed and I had to replace it. I restored the databases from backups, and changed the web.config file for tfs to point to the new server and most everything seems to be working. I can connect to tfs, do checkouts/checkins, create work items, etc. However, I cannot queue builds, and the event log is filling up with errors saying that TfsJobAgent cannot connect to the database. I was wondering if anyone knew if there was a way to configure TfsJobAgent to point to my new database. The event log details are below (TCOSRV1 is the machine running tfs, not the database server). Any help would be greatly appreciated.

Restoring to a new Data Tier (as it's called when you move between servers) needs to follow a quite extensive process to ensure that all settings are properly updated. The procedure would be the same for the process you'd use to migrate from one SQL Server to another.

The full process is explained here:
