Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
To boil advice down to a simplified version, try this:
http://<machine name>/ReportServer_<SQL Server instance name>
where the machine name is ***** *****'s name on the network, then SQL Server instance name is ***** ***** SQL server. Note that the last must be preceded by a _ (underscore character).
Something like, in your case,
But that is a URL for a web resource, not a proper reference for the Report Server to connect to... so, the point is, this way you get to a directory of elements published to Reporting Services. And this info may be entered in the Connect dialog for your Report Server.
Tell me whether I got that right, or whether that too does not work, please.
