Greetings to all members of this forum. I would like to describe the problem which I mess with.

I have Windows 10 x64 on my laptop Lenovo L450 which I use at office. At office I use Wi-Fi connection and VPN. The problem is I can't reach one folder which is shared locally on other Windows based PC (with turned on/off VPN). It's not because my antivirus (I use Bitdefender Internet Security 2016), and well I tried so many variants: I modified register, changed network share policy and etc. Nothing helped me.

Maybe you can suggest me something? Don't treat me bad, I am just new guy here, and I will update my topic and etc. in case something wrong with it.
