Solving error n8156-6003 when trying to play Netflix Watch Instantly content.

This is mostly search engine bait, because I couldn't find a solution on my own when searching, but managed to stumble across it anyhow.

I recently did a Windows 7 x64 reinstall, and after doing so, Netflix wouldn't play in any of my clients - Windows Media Center, Chrome, IE, you name it. After various solutions (DRM reset, security component upgrade, Silverlight uninstall and reinstall), it turns out the solution is stupidly easy:

  1. Run your browser as an Administrator. (Right click, Run as Administrator)
  2. Open Netflix and start watching a movie.
  3. Once it successfully starts playing, close your Administrator browser.
  4. Open a normal browser session and resume watching whatever you'd like to watch.

I can only guess that some initial setup doesn't get done properly, and it fails if you're trying to do the initial license acquisition in a non-elevated program. Hopefully this saves someone else a headache!
