The request failed with HTTP status 400: Bad Request ( The data is invalid. ): Code base Works on one machine but not another

This will probably be an environmental issue but I'm stumped as where to start.

I'm attempting to call a a webservice on an external server in an asp.net web app while debugging in VS2008. The exact same code/project works on one machine calling the server but on another machine (my new one) it fails with the 400 Bad request (data is invalid) error.

Both machines are running Windows 7. What should I be looking for as differences in the two machines that could be contributing to this problem?

Edit Deleting the webreference in the project and re-creating the webreference had no effect

Update

I went to use Fidler2 to inpect the request and response which resulted in the error going away. Things are beginning to point to an internet proxy issue.

It's an Internet Proxy issue. The suspect machine had be configured to manually use a proxy server. Turning this off: Control Panel -> Internet Options -> Connections Tab -> Lan Settings Button, and enabling "Automatically detect settings" has fixed the problem.
