For using a shared rec tv folder:

In the folders tab of serverwmc use the IP address rather then the machine name. So where it says enter the network path, substitute COMPUTERNAME for the IP address of your server.

For using HTTP:

Because this method is really NOT recommended for kodi you need to do one more step in order to get it to work, after turning on the http service. In the settings file of serverwmc (see debug tab) search for UseUrlClientPaths_Kodi and change the line its on to the following:
<UseUrlClientPaths_Kodi>true</UseUrlClientPaths_Kodi>

then save the file and restart serverwmc.
