How to share a folder on Windows 7 so your WD TV Live can actually see it I found this guide on another forum and it works I have also added some extra steps in as there were some missing.
Firstly, configure Sharing and Discovery:
1. Navigate to the Network and Sharing Center via the Control Panel
2. Click on the down arrow icons and select ON/OFF as follows:
Network Discovery - ON
File Sharing - ON
Public Folder Sharing - OFF
Printer Sharing - ON
Password Protected Sharing - OFF
Media Sharing - OFF
Secondly, Set up Folder Options:
1. Click Start then click Control Panel
2. Switch View By to Large Icons
3. Open Folder Options
4. Select the View tab.
5. Scroll down the Advanced settings list and uncheck “Use sharing wizard (Reccomended)” checkbox.
6. Click OK.
Next, configure the folder you want to share:
1. Select the folder
2. Right-click and choose ‘Properties’ from the menu
3. Click on the Sharing tab
4. Click the Advanced Sharing button.
5. Check the Share this folder checkbox
6. Click on the Permissions button
7. Everyone should be listed select everyone with the mouse and check the
full control, change, and read boxes.
8. Click OK
9. Click OK again
10. Next click on the Security tab in the Folder Properties dialogue box
11. Click the Edit button
12. Click the Add button
13. Click the Advanced button
14. Click the Find Now buttion
15. Under search results select Everyone and click the OK button
16. Under in the Group or User list select Everyone
17. In the Permissions List check all boxes and uncheck the
special permissions then click OK
18. Then click the Close button
Here are some further registry ‘tweaks’ if this doesn’t work:
WARNING: This requires editing your PC’s registry which, if edited incorrectly, can cause Windows systems to become unstable and unusable. So, follow the instructions below at your own risk.
1. Navigate to the following location in the registry editor.
MACHINE\System\CurrentControlSet\Control\Lsa</font>
2. On the right side, double-click on ‘everyoneincludesanonymous’ and change the ‘Value data’ from ‘0’ to ‘1’
3. Double-click on ‘NoLmHash’ and change the ‘Value data’ from ‘1’ to ‘0’
4. Navigate to the following location in the registry editor:
MACHINE\System\CurrentControlSet\Services\LanManServer\Parameters
5. Double-click on ‘restrictnullsessaccess’ and change the ‘Value data’ from ‘1’ to ‘0’
6. Close the registry editor
Finally, restart your PC.
Hopefully this will work. It worked for me!
