Thank you and I checked it and I do not see a ODBC Driver. However, I am able to connect to my SQL Server without any issues. I used

$dbh = DBI->connect( "DBI:ODBC:driver={SQL Server};Server=$server;Data
+base=$database;UID=$dbusername;PWD=$dbpassword", 
            { PrintError => 1, RaiseError => 1 } )

Also I noted another driver "SQL Server". Hope that handles the connectivity part.
