How to Enable Network Mapping in Windows 7
The network mapping feature comes handy in finding other computers and devices on the network, when your Windows 7 PC is connected to a domain. By default, Network mapping is disabled in Windows 7. Here is how you can enable it using Group Policy editor.
Note that Group Policy Editor is only included in Windows 7 Professional, Enterprise, and Ultimate editions. Hence this tutorial applies to only one of those editions of Windows 7.
1. Login to the computer with Administrator rights.
2. Click Start, type “gpedit.msc” (without quotes) in the start menu search box and hit enter.
3. In the Group Policy Editor, navigate to Computer Configuration > Administrative Templates > Network > Link-Layer Topology Discovery.
4. In the right pane, double-click on “Turn on Mapper I/O (LLTDIO) Driver”.
5. Turn on “Enabled”.
6. In the “Options” section, check the box that says “Allow operation while in a domain”.
7. Click “Next Setting” button.
8. Double-click on “Turn On Responder (RSPNDR) Driver”.
9. Click OK.
That’s it. Network Mapping should now be enabled.
