Problem with connecting on Raspberry Pi with OSMC

Hi there
I have Raspberry Pi 3B and I installed OSMC 2017.02-2. I connceted External HD (WD 2TB) on Pi and shared it on Network. Now i have a problem. On my PC i cant see this HD although in “Multimedia” part I can see my Pi (it is called MediaCentar) and I can connect. When I enter “\ 192.168.0.23/media” I get i message that it cannot be connected.
Smba is running.

Did you install the samba server from the MyOSMC app store?

yes.

You may need to reboot both the pi and the Windows machine.

You ware right. Im so stupid. Can you help me with something else? As you can see Im new in all this Rasbperry Pi and Linux world. My idea is to have Kodi (or OSMC) as a MediaServer and also to look LiveTV(free, stream and so on). Can I do that? Something like IPTV or add live streams? I tried one tutorial but in my version I dont have in TV Settings by General- Enable option (for PVR IPTv)
