Click on Start. Choose Run.
Type in what you see below:
\ IP ADDRESS (this is the IP address where the share is located on your network – no space after the \)
A window will open and if you see the share in that window – then all you need to do is type the IP and the share name in the share settings for the WiiMC.
That’s all I did to get mine working.
If you do not see the share in that window – you need to resolve that first.
