Thanks for the reply, I have figured out what my issue was, it seems that last windows update Build 16053.250 , managed to change my trust level in Norton firewall, I had to just go back into the firewall setting and re set all my devices to trust each other again.
I just mention it here in case anyone else experiences the same issue. And the OP since he has so many devices that this could be an issue that happens. Now he has my resolution to this issue.
