After a fresh reinstall of Windows I had similar issues in that my WD TV Live wouldn’t pick up my networked hard drives over LAN.
I checked the forums…like this one, and tried many different possible solutions, including renaming files and drives and resetting the WD player with a paper clip but no luck.
My cure? I unplugged the power from the back of the unit, disconnected the LAN cable, and gave it a minute, reconnected things, fired it up, and it immediately detected my two drives with my media. A couple of other little glitches were cured by a hard reset,
