How to send files via lan between two computers share (ok)

https://superuser.com/questions/689010/how-to-send-files-via-lan-between-two-computers

On the machine where you shared the folder, open the command prompt or type CMD in run (to open RUN in Windows use Key+R). Then type ipconfig (followed by enter) so you will get the IP-Address of that machine. Now go to another PC and open the run again and type \\ followed by the found IP-Address and press enter.

For instance:

\\192.168.15.1 and press enter

Remember to replace 192.168.15.1 with the IP-Address you found on the main-machine.

Edit:

You do need to enable the firewall to let traffic for file-sharing through. For ESET Smart Security you can look here for the settings to allow file-sharing etc.
