Re: Cannot open any HTTP URL (but HTTPS works!) after latest Windows Update

Frank,

Thank you very much for your response.

No, I do not have Windows Defender installed. I played around some more
and confirmed that I cannot access HTTP URLs using any version of MSXML
(I have MSXML 3.0 SP 5 and MSXML 4.0 SP 2). I wrote a simple test page
using AJAX and it could retrieve data over HTTPS connection but not
over HTTP using the Microsoft.XMLHTTP and Msxml2.XMLHTTP.3.0 objects.

Using the following KB article, How To Determine the Version of MSXML
Used by Internet Explorer, KB296647, I found that my IE uses
msxml3.dll.

I am very frustrated because I cannot understand what is broken and
why. The msxml3.dll seems to have the right version and unchanged since
2004. I tried reinstalling installing the latest version of MSXML 3.0
and 4.0, but this did not help.

I tried repairing Internet Explorer 6.0 installation (via Add/Remove
Programs, Internet Explorer 6 SP1, Change/Remove, Repair Existing
Installation) but that did not help either.

What else could I try?
