title: TFS - Cannot Check-In "big" files
body: <p>I've been working with TFS for months without a problem, now suddently I can't check-in "big" files (2kb files are ok, but 50kb files or multiple files are not). TFS is hosted on a server in the same network.</p>
  
  <p>When I try to check-in, it gives-me an error like: "<em>Check In: Operation not performed : The underlying connection was closed: An unexpected error occurred on a receive.
  Please refer to the Output window for more information</em>". The "more information" in output window is just the same error.
  The event viewer of the server shows nothing, and I've been looking in Google for the past couple hours and turned out nothing yet. </p>
