Add Advanced Sharing and Security Locations

In panel 5, 'Locations' I can only ever see the PC which the dialog box is located on, despite the ability to share with other PC's, moreover my laptop on some crossover ethernet.
Could somebody help or tell me how to add more locations here?
Alternatively, you could suggest some search terms that might yield better results. 'Share' Advanced' Windows 7 'Locations' just returns newbie guides to Windows 7 networking.

Thanks.

Im not sure I understand what you want....

The box you are seeing is configuring the network permissions. What you are seeing in that box, is Windows 7 asking what machine the file is hosted on (and the host controls the permissions).

Adding another Location would tell the network is stored on another computer... which it isn't

Example:
I have 3 machines, we will call them "Host" "Client 1" and "Client 2", a file called "Shared" is stored on "Host" The "Location" box tells the other machines that the File is stored on "Host" If the Location was changed, say to "Client 1" then if "Client 2" requested the file, it would (incorrectly) ask "Client 1" for the file rather than asking (correctly) "Host", which would obviously result in "Client 1" reporting that it doesn't have it, and thus produce an error message.

In Summary: There is nothing wrong with that picture, thats exactly how it is supposed to work, If it were possible to change it, you would break your network. As long as you give everyone permission from the Host machine then the file will share fine.

I hope thats clear enough for you.

Aha I see, My apologies, I misunderstood.

Quick question: are there machines/users on the network that you DONT want to have permission? or are you the only user on the network?

As I said, I dont think it can be done. Permissions are handled by the host machine, they dont take the network into consideration.

Few things I can think of that might work:

1. Try adding your username from another machine into the list (if its different) see if it finds it anyway. (you may have to put \\<other machines IP address>\<Username>

2.use an identical username and password on both machines. Give permission just to your username, and everyone else is set to "deny" that would probably work.

Or if number 1 doesnt work then and you dont want to use the same username, just give "Administrators" permission?
