I recently had a problem where someone changed the Reporting Services account in services which resulted in an symmetric key problem. We don't have a backup of the key.
I have deleted the key in order to create a new one with the expectation that I can re-input the datasource details. However I have an issue with the subscription. When I enter the report and click subscription I get the error:
The report server is unable to access encrypted data. Apply a back-up key or delete all encrypted content. (rsEncryptedDataUnavailable) (rsRPCError) Get Online Help
But I have already deleted the key and created a new one. Can anyone advise on what I can do to access this subscription. I have also tried the comman line rskeymgmt -d but have the same problem.
