How to resolve LAN Windows7 users and XP users can not exchange visits

For different operating systems in the LAN, it is common for them to be unable to access or share each other. For Windows 7 users on the LAN who cannot see the Windows XP machine, some netizens have given a seemingly "incredible" approach, even a "groundless" approach, but many users think this method is "sometimes very effective":

First, make sure that the workgroup and IP of the current Windows 7 machine are set correctly, and then go to network and sharing Center → advanced sharing settings to set the permission entries, such as Network discovery, network share, to allow or open.

Next, open an inaccessible Windows XP machine, generate a Network Neighborhood shortcut, and copy it to the current Windows 7 system (which you can copy to the desktop). At this point, when you double-click the Windows XP Network Neighborhood shortcut in this Windows 7 system, the current Windows 7 machine is available for normal access.
