Why can't the program access the file over an open Internet connection?

Question

I have two computers connected to a wireless network with no password.

The files are on computer A and the program is on computer B.

From the OS I can access and modify the files in A from B with no problem:

enter image description here

And when I run the program:

using (StreamReader sr = new StreamReader("\\\\VIERNES7-3\\Documentos c\\tables\\tableOrders"))
            {
                String line;

                while ((line = sr.ReadLine()) != null)
                {
                    activeTables.Add(int.Parse(line));
                }
            }

It gives me the following exception:

No se controló System.UnauthorizedAccessException
  Message=Access to the path '\\VIERNES7-3\Documentos c\tables\tableOrders' is denied.

I'm not sure what is the problem since I seem to be authorized.

Is tableOrders a file? StreamReader must take a file name. It's a little odd to have no extension. — Mike Zboray, Jun 02 '12 at 04:22

If you cut and paste the path into explorer, remove the extra slashes, does it open the file?

How are you running the program (in debug mode?)?

Have you tried running the program and Visual Studio as Administrator?

Does it work if you set up a new share in c:\ with Everyone permissions?

Why can't the program access the file over an open Internet connection?
