We had a server give out on us completely. All that is left is a back up of the SSRS database. We have been able to get a new SSRS environment working but the symmetric key doesn't seem to work. Reports will run if we delete all sensitive data through the Config manager and reenter the connection strings into the datasource but if we can get the symmetric key saved in the ReportingServices database to work correctly it will save us a ton of effort.
Can we make use of the symmetric key saved in the ReportServer.dbo.Keys table?
