Displaying a pdf on a network share via a link

I am trying to display a pdf via a link but I can't figure out how to address it. I can display the image in both ie and firefox with this:

\\192.168.nn.nn\sharedfolder\folder\200211ACD\AX2F0345\0247.PDF

But when I code this:

<a href="\\192.168.nn.nn\sharedfolder\folder\200211ACD\AX2F0345\0431.PDF">SS9230</a>

I get this in my address bar:

localhost/\\192.168.nn.nnn\sharedfolder\folder\200211ACD\AX2F0345\0429.PDF

But when I copied it to paste it here it looked like this:

http://ift.tt/1EzB4F5

I tried prefixing it with "http:" but this did not work either. I have a local copy of wamp installed and do not know if this is interferring in any way. I had someone else try and they can get a directory listing by entering " \\192.168.nn.nn\sharedfolder". I just want a page with links to images on a share to be able to display them.
