HTTP/1.1 400 Bad Request

I have a problem with an automated system that gets
updates from a web server. I have used this system for a
few years now working just fine until I updated the web
server to windows 2003. It is a get command that this
error happens on. I ran net monitor on the webserver and
the packet is ok. The Url and all the info in the header
acording to Net Monitor is correct. Now I have gone back
to older versions of IIS 4.0 - 5.1 on older windows
version and it works just fine. Is there some reason for
the error other than corrupted packet? Please help I need
to keep the upgrade to windows at 2003 for other projects
that are now working. But I also have systems out there
that need the update functions to work as well and can't
setup older IIS's to service them.

One set of requests that would have worked on previous versions of IIS but
would be 400 on IIS6 are requests whose lines are terminated by only \n and
not \r\n as per HTTP spec.

If you can post the entire request from NetMon (as well as the response),
that would help tremendously.
