I'm Getting the "Could not connect to server: The type initializer for 'System.Data.SqlClient.SqlConnection' threw an exception" Error on an existing Instance of SSRS that had been working previously (lots of installs/patches since).
Any time I try to hit the "Test Connection" button on existing connections or create new ones from the SSRS Config Mgr., it throws that error.
I know the SQL Server connectivity works (I have SSMS installed on there and can cut and paste server Login to connect). The problem is I can't really get any more details on the error...Event Viewer isn't logging anything, I have upped the trace level
to 4 in the reportingservicesservice.config file, I have even watched it with procmon and nothing obvious pops up.
Let me know if anyone else has been down this path and what they have tried.
