I don't understand this error:

Response object error 'ASP 0156 : 80004005'

Header Error

/yadayada/Default.asp, line 8

The HTTP headers are already written to the client browser. Any HTTP header modifications must be made before writing page content.

And the code of the asp is:

<HTML>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso-8859-1">
<HEAD>
<TITLE>
</TITLE>
</HEAD>
<BODY>
<% Response.Redirect "top.htm" %>
</BODY>
</HTML>

What's wrong? It worked on my home personal server (NT5) but doesn't work in school's server (NT4).
