Thanks for posting. I tried those without success.
What I did find is that if I invoke ie from the cmd or from a folder
address bar, then ie will launch and the first web page will display
without the error....but if I click any links, then I get the http 400
error again on any link.
Example: If I type "iexplore 192.168.0.1" in the Start, RUN....then
the web page will display.
Or if I open "My Documents" and pit "192.168.0.1" in the address bar,
it will work too.
But if I start IE and then type in 192.168.0.1 (or
http://192.168.0.1),
then I get the HTTP 400 error. Firefox does not have this problem.
