Unable to form socket connection in php under IIS6

I am configuring a Windows Server 2003 machine to run php. The system is currently running IIS 6 and is hosting several active websites. I am able to get php to run but when I attempt to connect to a database I receive the error "Failed to connect to MySQL: A socket operation was attempted to an unreachable host. "

This happens with any attempt to create a socket connection. The code I am using works on another server, so I know there are no errors in my code.

<?php
$debug = true;

	
function dbPDOConnect($dsn, $dbName){
    global $db, $debug;
		$db_usernameAdmin = *********;
		$db_passwordAdmin = **********;
   
    if (!$db) $db = new PDO($dsn . $dbName, $db_usernameAdmin, $db_passwordAdmin); 
  if (!$db) {
    return 0;
  } else {
    return $db;
  }
} 

function connectPDO($dsn,$dbName){
		global $debug;		

		$query      = NULL;

try { 
  	  $db=dbPDOConnect($dsn, $dbName);
  	  if($debug) print '<p>You are connected to the database!</p>';
		} catch (PDOException $e) {
   		 $error_message = $e->getMessage();
    if($debug) print "<p>An error occurred while connecting to the database: $error_message </p>";
		}

}
connectPDO('mysql:host=webdb.uvm.edu;dbname=','LTOPPER_CS148_Final');

?>

I cannot find any information on this problem. Has anyone encountered this problem before? Are there any changes I can make that will allow outgoing connections?
