SQL Server 2012 - Cannot connect to SQL Alias (Connection to serverName is good)

Hi there,

On my 64 bit installation of SQL Server 2012 - I have enabled SQL Alias using cliconfg 32 bit and as well as on cliconfg 64 bit.
On my WFE (Web Front End server) I have set the SQL ALias as well (both 32 bit and 64 bit).

From WFE (Web Front End) server I can ping the SQL server name but cannot ping the SQL ALias. Any clue what I might be missing?

Thanks.
