Link to file in network working in browser but not in HTML Site

Question

I am facing a strange problem right now:

I got a link to a file on a network in the following format:

file://///server.com/awesome/route/to/file.wav

(I used the 5 Slashes as suggested in this Thread)

When I copy & paste the link in the browser, it works like a charm. But when I include the link in my HTML Page with

<a href="file://///server.com/awesome/route/to/file.wav">Link</a>

the link is not working. There is absolut no reaktion of the browser. He does not even try to access the file.

Tested with:

Chrome and Firefox on Windows 7
