I have a SQL 2014 SP1 Standard Edition installed and running on Win 2012 R2.
SQL SSRS Reporting services are all setup, configured, running (all in native mode) and I can access and run reports on it fine.
I can access both ReportServer and ReportManager URL's no problem.
I cannot use SSMS <started and running as (Administrator)> to connect to the Reporting Service to manage ROLES, etc...
I tried my NT Domain account which is part of Local Admins, the NT Local Admin account that is running both SQL and Reporting services and SA but all fail with the error below:
The username or password is not valid or you do not have permission to access this server. (Microsoft.SqlServer.Management.UI.RSClient)
What can/should be done in order to access/manage "Reporting Service" via SSMS 2014?
