Today working on a client’s SCCM 2012 installation came across this issue. During the Configuration Manager 2012 reporting services setup noticed that the instance name is blank which halted my installation. This usually occurs when SSRS is installed but not configured properly.

Generally there are few folks involved in the installation of SCCM, it is often seen that the reporting services were installed but was not fully configured for the SCCM reporting services. So, here is what you need to do in order to populate the instance name:

1.Open Reporting Services Configuration Manager – Start – Programs- Microsoft SQL Server 2012 – Configuration Tools – Reporting Services Configuration Manager
2.Connect to the server/instance
3.Go to Web Service URL – In the SSL certificate select “ConfigMgr SQL Server Identification Certificate, if it is blank. current date time And then click Apply. This will then create the new virtual directories.
4.Go back to the SSCM Servers and Site System Role, click “Verify” for the database connection to populate the instance name if not already populated.
