Unable to connect to the SQL Server 2005 (with SP3) running on Windows Server 2008 R2 through the SQL Server 2014 Management Studio

Hi,

We have installed a new SQL Server 2005 (with SP3) on Windows Server 2008 R2. We are unable to connect to the SQL 2005 Server through SQL Server 2014 Management Studio. Is this supported? All SQL server 2005 services except for AD Domain helper are running on the server.
