So basically I have a PHP server that runs PHP all fine and I have a MS SQL server which has been used to host backends of Access Databases. Now we want to also have a web interface to this backend and I am trying connect to the database through PHP but can't seem to get it to work. Do I need to do something, here is the code I am using.

$hostname = "\PLYSVSQ017\";
$Username = "sa";
$Password = "password";
$DBname = "Test";

//connection to the database
$dbhandle = mssql_connect($hostname, $Username, $Password)
or die("Couldn't connect to SQL Server on $hostname");

Upon failure I don't even get the Couldn't connect error showing??
