Technically: The IIS7 plugin notes that IIS itself has returned "E_INVALIDARG" when it was called back at IHttpRequest::SetHeader. The IISplugin has logged this to the event viewer and signalled the error back into the rest of the system.
There is absolutely no indication in the programming manual for that method as to what would provoke this error statusL
The best that we as a project can do is to add more logging to the next version of the SP so that you will see the header name that was trying to be set and the value - but we need to JIRA case to remind us to do this.
