   GO

   UPDATE ConfigurationInfo SET Value = 'True' WHERE Name = 'EnableRemoteErrors'

3. Restart Reporting Services on the server: Click Start > Administrative Tools > Services to open the Services management console. Right-click the SQL Server Reporting Services ([InstanceName]) service, and then click Restart.
