Connect to MSSQL

[p23]

Hello,

I've installed XAMPP 1.8.1
OS: Windows Server 2012 R2

I've added the extensions in php.ini
;;;;;;;;;;;;;;;;;;;;
; MSSQL Extensions ;
;;;;;;;;;;;;;;;;;;;;
extension=php_pdo_sqlsrv_54_ts.dll
extension=php_sqlsrv_54_ts.dll

Restarted the server...

But the extension are not loaded
What did I missed out?
Thank you.
