In my LAN configuration the Auto LAN Search option in the Media Center and the SMB Source Search inside KODI doesn't work at all, shows just the "Server Error and No Source" message. Manually typing in the Source IP and folder name works, but it's still strange.
The share is on a Windows 7 notebook, network and folder sharing all setted up correctly (by my knowledge) and from the notebook I can see the media box's IP too. I have a router in the chain and using Norton Internet Security on Windows. Gived full traffic permissions to the media box IP and setted it's Trust Level to Trusted in the NIS firewall. Also tried to turn off the NIS protection functions completely, but it still didn't work.
I had made a separate thread according this back a while, but with some hope I thought to mention it here too.
Thanks if someone has any idea to resolve it!
