如何从php(其他计算机）连接到sql server

我安装了一台计算机sql server 2005
和其他计算机安装xampp v3.2.1
我试图通过php在计算机安装xampp中连接到sqlserver2005，但没有工作。

在计算机安装示例：

我从以下位置下载适用于php的驱动程序3.0http://www.microsoft.com/en-us/download/details.aspx?id=20098

并将2个文件php_sqlsrv_54_ts.dll和php_pdo_sqlsrv_54_ts.dll复制到Xampp'php'ext
我将下面的代码添加到php.ini 中

[sqlsrv]
sqlsrv.LogSubsystems=-1
sqlsrv.LogSeverity=-1
sqlsrv.WarningsReturnAsErrors=0
extension=php_sqlsrv_54_ts.dll
extension=php_pdo_sqlsrv_54_ts.dll

i通过测试连接

$serverName = "nameserver";
$connectionInfo = array("Database"=>"namedatabase");
$conn = sqlsrv_connect($serverName, $connectionInfo);
if ($conn) {
    echo "success";
}else {
    die (print_r(sqlsrv_errors(),true));
}

但是我得到错误
