Windows 7 into an XP LAN

First thing to do is make sure all of your computers are in the same "Workgroup".

- Default workgroup set by Windows is WORKGROUP. You may have changed it.

- In Windows 7 click Start then Control Panel.

- In Control Panel click on Network and Internet and then click on Network Sharing Center.

- Over on the right click on Change advanced sharing settings.

- Click the button next to Turn on network discovery.

- Click the button next to Turn on file and printer sharing.

- Click the button next to Turn on sharing so anyone with network access can read and write in the Public Folders.

- If you don't want users on your network to have to enter password then click the button next to Turn off password protected sharing.

- Click Save Changes.

- Now, click Start and then Computer.

- On the right side click Network and you'll see all of the PC's running XP, Windows 7, Vista, and more.
