User domain\user does not have required permissions during SSRS configuration

I have installed SQL Server Reporting Services and configuration went smoothly. But I have received below error while trying to open the Repots URL i.e http://servername/Reports

User domain\user does not have required permissions. Verify that sufficient permissions have been granted and Windows User Account Control (UAC) restrictions have been addressed

Below posts helped me to resolve the issue.
