It is filled with Spamqand I'm the only regular here, but I answer most
(i.e. all 3 different :-) questions ...

You are using

  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"  
  "xhtml1-transitional.dtd">

Your system identifier should point to

  http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd

instead of http://www.unrealsystems.com/xhtml1-transitional.dtd
especially because it points to a false location:

% http-head http://www.unrealsystems.com/xhtml1-transitional.dtd
HTTP/1.1 302 Object Moved
Location: /
Server: Microsoft-IIS/5.0
Content-Type: text/html
Connection: close
Content-Length: 124

<head><title>Document Moved</title></head>
<body><h1>Object Moved</h1>This document may be found <a
HREF="/">here</a></body>

This is twice broken, the Location:-HTTP-Header must return a absolute
URI, not a relative one and response entity bodies are forbidden for
HEAD requests.

However, fixing your SYSTEM identifier should solve your problems with
the validator in the first place.

Maybe this is because the two

  Page-Completion-Status: Normal
  Page-Completion-Status: Normal

headers in your HTTP response (resulting in

  Page-Completion-Status: Normal, Normal

...), however, the validator encounters currently violent network
errors, i.e. most hosts aren't reachable, www.w3.org for example.

Another source for errors is the

  Content-type: text/html

header, this should be text/css for CSS files, another thing to fix.

Maybe then the right MIME type is returned by your IIS server, but
normaly the Validator should say that the resource has the wrong MIME
type...
