localnet access

Hi,
I'm trying to access the files in a directory of another pc in the intranet. The problem is that the access to this pc requires a password. I'm using a filechooser to do this. When i press the button to access the files of this directory nothing happens! I would be very happy if someone could give me an advise of what can i do to get at least a prompt to enter the password and get in!
Thanks in advance

I've deleted the other copy of this you just posted to the I/O forum. Please see this document for an explanation.

Regarding your question: this is utterly specific to whatever operating system you're working with -- I'm assuming you're talking about Windows "shares", but it could be anything. You won't get any useful answers without describing your problem with some more specific details about the platform.

Sorry, I hadn't read that rule.
About the problem: I'va made a mistake. I'm trying to access files in an intranet (not a localnet as i wrote by mistake).
There are some p/cs in a building and some others in another. All the p/cs run Windows XP.
I want to make an application to access the files of every p/c in the intranet. I can do it with the search option of Windows just by searching for example (\\192\168\c:\...).
Some of the p/cs require a password so i just type in when Windows ask for it in the prompt box.
Now in my application:
I'm using a FileChooser and i'm entering the IP address in the "File name " box. When no password is required i can see the files of the directory that I want.
But when password is required nothing happens. I guess it will be a way so that to be prompted for the password ang simply get in. I copy->paste below some of my codes
to help you understand what I'm looking for.

...
fc=new JFileChooser();
fc.setFileSelectionMode(1);
fc.setControlButtonsAreShown(false);
....

(in ActionPerformed method)
fc.setCurrentDirectory(new File(path)); //where path is the IP address that I want to access

I later use a FileReader and a BufferReader to read the files in the directory of the remote p/c

Hope to help you understand. Any advice will be much appreciated.
