I have a jsp page that displays a title, an image and a paragraph. It was doing fine until recently. About 40% of the IE browsers display only the source code instead the actual page, the otehr 60% are fine. Can somebody tell me if it's a configuration problem or is there any syntax in my jsp code?

Here is the code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
<%@ page contentType="text/html;charset=UTF-8"%>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<style type="text/css">body {background-color: #ffffff;}</style>
<script language="JavaScript">
window.onhelp = new Function("return false;");

function IgnoreKeys(event)
var keynum = (window.event) ? event.keyCode : event.which; // IE or NE

event.keyCode = 8;
event.cancelBubble = true;
event.returnValue = false;

if ((keynum == 13) || (keynum == 32)) // Spacebar or Enter key.
<body onload="document.Form.Next.focus()" scroll=no onselectstart="return false" oncontextmenu="return false;">
<form name=Form method="post" action="MainProcess" onkeydown="IgnoreKeys(event)"
style="font-family:Times New Roman; font-size:18.0pt;">
<table cellspacing="0" cellpadding="0" border="0" width="100%">
<tr><td align="center">
<br><br>SAMPLE PAGE<br>sample page</td></tr>
<tr><td height="123">&nbsp;</td></tr>
<tr><td align="center"><img src='loadlogo' alt="No image available"></td></tr>
<tr><td height="235">&nbsp;</td></tr>
<tr><td><table cellspacing="0" cellpadding="0" border="0" width="95%"align="center">
If this is your correct name, click the Next button or<br>
press the ENTER key to continue. Otherwise, raise your hand for help.</td>
<td valign="bottom" align="right">
<button name="Next" type="button" onclick="submit()" style="font-family:Times New Roman;
font-size:18.0pt; background-color:rgb(230,225,220); height:53.0px;width:160.0px;">
