What is error code is 0x80070001? And how can I solve it?

Question

I'm getting this error on my web service:

An error occurred while communicating with the remote host. The error code is 0x80070001

The weird thing is that the CPU and memory usage on the server is not high.

The detailed error message:

Error Message:

An error occurred while communicating with the remote host. The error code is 0x80070001.

Stack Trace:

After Google Search:

How can I fix this problem?

More information

Inner Exception Message: The handle is invalid. (Exception from HRESULT: 0x80070006 (E_HANDLE))

Very Important

This is only happened with a web application, but if I used a web site, nothing happened (no error).

And after a lot of research I think this error is caused by the web.config file.

Solution

I receive this error on my site also. I've determined the agent that generally causes this problem and it is a webcrawler like the one used by Google to index pages.

Anyway, I believe the answer is either Cause 1 or Cause 2:

Cause 1

This problem occurs because the client makes an HTTP request by using an HTTP method that does not comply with the HTTP specifications.

Cause 2

This problem occurs because a client makes an HTTP request by sending the POST method to a page that is configured to be handled by the StaticFile handler. For example, a client sends the POST method to a static HTML page. However, pages that are configured for the StaticFile handler do not support the POST method.
