Answer 1

This is happening because there is an unhandled exception in your Web service, and the .NET runtime is spitting out its HTML yellow screen of death server error/exception dump page, instead of XML.

Since the consumer of your Web service was expecting a text/xml header and instead got text/html, it throws that error.

You should address the cause of your timeouts (perhaps a lengthy SQL query?).
