Here is my php code that is throwing this error:
$serverName = "***********************";
$connectionInfo = array( "Database"=>"*********", "UID"=>"*********", "PWD"=>"*************");
$maxret = 3;
$conn = false;
do {
$conn = sqlsrv_connect($serverName, $connectionInfo);
if($conn !== false) break;
sleep(2);
} while($maxret-- >= 0);
I have installed ODBC related libraries
I'm working on three different machines, with different IP addresses, all enabled on azure firewall (sql database is on azure). On one of the machines it works, two of the machines generates the error above.
Identical php.ini files on two of the machines and in wamp the listed extensions are the same. On one machine the php script runs, on another it generates an error.

The solution to this problem was to install Microsoft SQL Server Management ...
