Ok, lets try to avoid confusion here. Most people seem to report that they have an issue to access SMB shares (without username and password) that they have running on their NAS or Windows PC from their OSMC Box.
It sounds like you are reporting to have an issue the otherway around means accessing the shares on the OSMC from your PC.
- Please confirm and give exact detail of the PC your are trying to connect from to OSMC
- Provide the journal log
