With the upgrading to Windows 10 I had the same problem as many of here not being able to share media content from my PC onto WDTV Media Player.
After playing around for a while with various settings I found a solution that is working, at least for me:
On your WDTV: Setup —> Network Settings —> Clear Saved Network Share Login —> Clear All Windows Share Login —> OK
On your PC:
a) right click START —> Control Panel —> Network and Sharing Center —> Change advanced sharing settings —> All Networks (drop down arrow) —> Turn off password protected sharing (last one on the bottom) —> close everything.
b) right click START —> File Explorer —> navigate to the folder you want to share and right click on it —> Properties —> Sharing (tab) —> Share… (NOT Advanced Sharing…) —> in the new opened window there is a large empty box with a drop down option on the right side. Click the arrow and select either Guest, Everyone or both of them —> after each selection click Add —> for Guest and/or Everyone set bellow Read/Write Permission Level (this is very important because WDTV needs to right some media library information inside your shared directory) —> Share
In my case it’s working with just a Guest account permission.
- Now you should be able to find the shared directory on the WDTV.
Also, I don’t know if this counts, but I did all this on a fresh/clean install of Windows 10 Home. The upgrade process left to many c.r.a.p. on my C:\ partition.
I hope this helps everyone who has the sharing problem. Good luck and enjoy!
P.S. I’m from Romania so I apologize for the eventually english mistakes.
