How does wyUpdate download via HTTP?

What method does wyUpdate, when deployed with my software, use to check via HTTP for new patches? I am having a problem on a machine downloading the latest wys file from our webserver during an update check. This same machine is having a problem connecting to the internet with IE, but HTTP requests seem to be working fine for other software, like our own webservice calls. They use the lower level HTTPWebRequest object.

I'm guessing you might be using the WebBrowser object, which is basically a wrapper for IE in my experience. If IE is broken, the WebBrowser may be broken, meaning we cant get updates.

I just need to know what is going on internally so I can find out if I can do anything about it.

The wyUpdate error message:Error : Checking for update failed. Reason: Unable to check for updates, the server file failed to load.. Message: Error trying to save file: Error downloading http://OUR_WEBSITE/wyserver.wys": The server committed a protocol violation. Section=ResponseStatusLine.

FYI, your software is working very well and is surprisingly easy to integrate. Keep up the good work.

No, we use the HttpWebRequest object as well.

Is this happening on other machines, or is it just a single machine?

It is the only machine that we have noticed it for so far. I'm going to assume the OS is just compromised and not worry about it unless we see the same problem elsewhere.
