title: Call to undefined function mysql_connect()
body: <p>I have a windows 2003 server with IIS 6 and mysql is on another machine. We just recently upgraded from PHP 5.1.6 to 5.3.27 and we have 250+ clients and this is the only client receiving this error. Can you tell me why this error would be happening?</p>
