Q:

The specified network name is no longer available?

I want to play a local video file from nancy embedded http server. It is OK to read a txt file but once it tries to open a video file it gives error :

"The specified network name is no longer available" 

on the line 
return Response.AsStream(() => File.OpenRead(@"E:\test_videos\test.mp4"), "video/mp4");

I can play the video from my browser, so what is wrong then?
Update: I could play video on FireFox and IE, the error only occurs in chrome.

A:

I have implemented mp4handler for nancyfx and it worked.
