Accessing Reporting Services Using a Fully Qualified Domain Name

If you installed SQL Server Reporting Services (SSRS) on a server in a domain and you use a domain user to start the service and did not perform any further configuration, then you most probably can only access the Report Manager using an IP and not the Fully Qualified Domain Name (FQDN) of the server (if an SPN is not set).

If you try to use the Fully Qualified Domain Name to access reporting services then you will most probably be prompted for username password several times ending with an empty page.

How to Enable Accessing Reporting Services Using a Fully Qualified Domain Name

In order to be able to access Reporting Services using FQDN you will need to perform the following actions:

1. Register a Service Principal Name (SPN) for the Domain User Account that Runs SSRS

Consider the following example:

sample computer name: reportsrv01
sample domain: example.com
sample domain account: examplessrsuser

Then on the Domain Controller Server in a Command Prompt with Elevated Rights, you can Run as Administrator:

example 1: If SSRS are on port 80 (no need to specify 80 as it is the default http port):
Setspn -s http/reportsrv01.example.com examplessrsuser

example 2: If SSRS are on any other port (i.e. 2430):
Setspn -s http/reportsrv01.example.com:2430 examplessrsuser

2. Edit the RsReportServer.config File

On the Reporting Services server, in the virtual directory of SSRS, edit the “RsReportServer.config” file and locate the authenticationtypes section.

Then add </rswindowsnegotiate> as the first entry in the authenticationtypes section.

The above step will actually enable NTLM.
