I am using Windows Small Business Server 2003 with IIS 6.0.  I am attempting to connect to a mysql database using the following code:

$conn = mysqli_connect('192.168.1.x', 'root@localhost', 'password', 'database');

I have also created another user account, and provided all privileges to the account in the MySQL client.  I then tried connecting with the new user account with the same error message

Warning: mysqli_connect() [function.mysqli-connect]: (28000/1045): Access denied for user 'root@localhost'@'cogent-s1.CogentMedia.local' (using password: YES) in C:\StuffLocator\email_verification.php on line 20
Access denied for user 'root@localhost'@'cogent-s1.CogentMedia.local' (using password: YES)

I have checked the php.ini to ensure that the extension=php.mysqli.dll is uncommented and that the php.mysql.dll is in the extensions folder.

I appreciate all help that can be provided.

Hi,
      can you try this

$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = 'password';
$dbname = 'databaseName';

$conn = mysql_connect($dbhost, $dbuser, $dbpass);
mysql_select_db($dbname, $conn);

just give tn user name as root no need the domain like root@localhost

I noticed that you are using mysql_connect instead of mysqli_connect (with the i after the mysql part).  My reading has taught me that mysql is for older versions of PHP and MySQL, and does not include all of the new functions and OOP properties of the mysqli package.  

I tried using variables instead of place just the values into the mysqli_connect method:

$localhost = 'localhost';
$username = 'root';
$password = 'password';
$database = 'db';
 $conn = mysqli_connect('$localhost', '$username', '$password', '$database');

and got this error:

Warning: mysqli_connect() [function.mysqli-connect]: (HY000/2005): Unknown MySQL server host '$localhost' (11004) in C:\StuffLocator\email_verification.php on line 24
Unknown MySQL server host '$localhost' (11004)

Is there something that I have to do in the MySQL client to get the localhost linked to the database?

t tried the following code:

$localhost = 'localhost';
$username = 'root';
$password = 'ljfs531ljfs531';
$database = 'test_001';
 $conn = mysql_connect('$localhost', '$username', '$password');
mysql_select_db($database, $conn);

and received the following errors:

Warning: mysql_connect() [function.mysql-connect]: Unknown MySQL server host '$localhost' (11004) in C:\StuffLocator\email_verification.php on line 24

Warning: mysql_select_db(): supplied argument is not a valid MySQL-Link resource in C:\StuffLocator\email_verification.php on line 25

This was using the older mysql_connection. any ideas

Hi,
      when using variable you don't have to use single quote
instead of
 $conn = mysqli_connect('$localhost', '$username', '$password', '$database');
use
 $conn = mysqli_connect($localhost, $username, $password, $database);
