I am kind of newbie to SSRS configuration side. We are using SQL server 2008 R2. The reporting services are running in amazon provided cloud environment. Some how the DB port was not opened for external use so we had to create the reports in Cloud server system itself and thus I always gave datasource connection string to use localhost server with windows authentication. every thing worked well until today when cloud team has separated the DB server. After this I changed the connection string of the datasource with new DB server and changed it to sql authentication and re-deployed it. but still I get the error when I try to access the report from report url. " Login failed. The login is from an untrusted domain and cannot be used with Windows authentication" I don't know what are the right steps to follow after DB separation and so I am kind of lost. Any help is highly appreciated. Thanks
