System.Runtime.InteropServices.COMException Incorrect function. (Exception from HRESULT: 0x80070001)
See the question and my original answer on StackOverflowThis is an error reported by underlying unmanaged layers of IIS7 (webengine.dll). After some googling, the most relevant thread seems to indicate this is an error due to the network card driver configuration (TCP Offloading).
See this: An error occurred while communicating with the remote host. The error code is 0x80070001
