Under the Registered Servers window, I switched to Reporting Services and created a new server registration. By way of trial and error I figured that the Test button would succeed if I entered http://ip_address/ReportServer for the server name (the IP alone or a full URL of the SSRS ASMX would not work), chose Basic or Forms Authentication and provided the user name and password. Then it tested Okay and saved.

Now that I am trying to connect to the newly registered server, I get the following error:

TITLE: Microsoft SQL Server Management Studio

Error connecting to ''.


Value does not fall within the expected range. (Microsoft.SqlServer.Management.UI.RSClient)

I noticed that after I save the new server registration, the Authentication drop down always reverts to Windows Authentication and blanks out the user name and password, even though I am specifying Forms/Basic, testing that successfully, and saving thereafter.

What am I doing wrong?

  • Use windows auth and server name syntax should be servername\instancename. – Daniel Björk Aug 2 '17 at 15:40
  • To use Windows auth I would need to be a user on the SSRS server, which is not the case. – ajeh Aug 2 '17 at 15:46
  • Then someone who are need to configure basic or form authentication and add you in such way before you can use them. They are not default settings for SSRS. – Daniel Björk Aug 2 '17 at 15:49
  • Read the section about register a report server. docs.microsoft.com/en-us/sql/reporting-services/tools/… – Daniel Björk Aug 2 '17 at 15:51
  • And you don't need to be a user in the server but you need to be added as a user in SSRS to be able to connect. – Daniel Björk Aug 2 '17 at 15:55

Form and Basic login must be configured before you are able to use them and SQL Login is not supported. https://docs.microsoft.com/en-us/sql/reporting-services/security/authentication-with-the-report-server

  • When using the syntax you proposed, the login times out. And the saved server is still reverting to Windows auth. What am I missing? – ajeh Aug 2 '17 at 15:36
  • You need to use Windows auth like i wrote or Configure form or basic. – Daniel Björk Aug 2 '17 at 15:37
  • Do you know the instance name? – Daniel Björk Aug 2 '17 at 15:38
