Can't make alias of a nework location in WAMP Apache

Question

This is vgs5.conf saved to C:/wamp/

Alias /vgs5/ "//Serv-lt/vgs5" 

<Directory "//Serv-lt/vgs5">
    Options Indexes FollowSymLinks MultiViews
    AllowOverride all
    Order allow,deny
    Allow from all
</Directory>

When I go to [http://127.0.0.1/vgs5] using firefox it shows me the directory contents. When I go to [http://127.0.0.1/vgs5/xxx.pdf] using firefox it shows 404 Not Found. Although the file xxx.pdf does exist and is viewable at \\Serv-lt\vgs5\xxx.pdf in adobe.

WampServer Version 2.2
Apache 2.2.22

Answer 1

This is what worked

Alias /vgs5 "//Serv-lt/vgs5" 
<Directory "//Serv-lt/vgs5">
    Options Indexes FollowSymLinks MultiViews
    AllowOverride all
        Order allow,deny
    Allow from all
</Directory>
