I have two machines - Windows XP and a laptop using Windows 7. I connected them with a WLAN cable.

On the Windows XP machine, I set the IP address to On the Windows 7 laptop, I set the IP address to

The laptop can see the Windows XP machine, but Windows XP machine cannot see the Windows 7 machine. But this does NOT concern me. I want to move the files from my desktop (Windows XP) to Windows 7 (laptop). That's why I'm going through all this.

The problem is that when I try to connect from Windows 7 to Windows XP machine, I get this window:

I don't understand what username/password is needed. I use none on the Windows XP machine. I tried all usernames - no success.

Please explain in deep details how to solve my problem so I can connect to my Windows XP machine.

EDIT: Maybe this can help: the Windows XP machine is named 'I' and 'Проданов III' is the name of the laptop. Both computers share one workgroup - WORKGROUP.

Not necessarily related, but to make XP see Windows 7 open the Network and Sharing center and click on Customize to make the network a private network, you should then be able to see both ways. –  heavyd Mar 10 '10 at 17:35
That actually is quite related. Windows 7, by default, marks networks it doesn't know as public and sharing without passwords is disabled. If you mark a network as private, I think it should work. –  Zsub Apr 9 '10 at 9:08

  1. Find your username for I
    • Ctrl-Alt-Delete, it may show you the username as "you are logged in as I\USERNAME", or it will bring up the Task Manager.
    • If you see task manager, click on Users tab, that will give you the name that's logged in.
  2. Set a password
    • Your account on I must have a password.
    • Start -> Control Panel -> User Accounts, then select your account and set a password.
    • While you're there, make sure this user is an administrator - it remove a lot of permission problems
  3. After setting the password, reboot. Always reboot when in doubt.
  4. Try connecting again from laptop
    • Username is I\USERNAME, whatever you found in step 1
    • Password is the password you just set

Put in your account name used on the Windows XP machine and leave the password field blank. Domain needs to be the Windows XP computer name.

Username: I\XPUser

I have had mixed results with Windows 7/Windows XP connectivity. Usually something gets weird in the 7 box and once I restart it, it works fine.

On the Windows 7 laptop can you try to navigate to \\c$ ?

However, I do believe, you will need to set a password on the Windows XP machine for file sharing to work. You can use something simple temporarily like "p@ssw0rd" Warning: Please set a strong(er) password on the 2 machines. But, hey, they are your machines do what you want :).

OTHERWISE, you can set the permissions on the share to Everyone Allow -> "All", which will literally allow EVERYONE to have access which I wouldn't do especially if you forget to turn it off.... Again, they are your computers do what you want, but you have been warned :).


As a side note, do you have a share which you gave your user permissions to it?
