Thank your for the link.
I did a couple of hours research last day and finally i found a way to fix it. i will all explain in here so maybe it will help someone else with the exact same problem.
-- First u need to install gedit with it respective command from terminal ( sudo apt-get install gedit ).. than after u successfully install it u need to open from terminal the path : sudo gedit /etc/samba/smb.conf..
After entering this command a notepad will appear. In this file if u search u will see : workgroup=workgroup ,,,, and right under this u will need to add this line** name resolve order=bcast host. And it will be like this :
workgroup=workgroup
name resolve order=bcast host.
After this just save the file and the Network share folder with be OK.
And if u will need to add a folder to xUbuntu desktop from the shared folder , just open the respective folder in the share and copy his link location , and afer u can creat a folder with this lick location to desktop by righ click-ing it.
Thank again for your support everyone, have a nice day and holiday , and christmas
