TOPIC: Windows 10 Version 1511 and SMB3

Hi,

Windows 10 Version 1511 update start rolling out.
So far I got it in two machines and both share similar behaviour.
If SMB3 is enabled, NAS is not visible in Network Places also net view on computer returns Error 1231.
Switching to SMB1 on NAS cures the problem.
Netbios is enabled on computers as well Network Discovery and Client for Microsoft Networks.
Workgroup is same on all devices and NAS itself is only Master Browser in network.
PIN login is not used and Homegroup setting is set to "Use usrname and password".
PC`s which have not recieved this update work as they should, even when SMB3 is chosen on NAS
Anyone has and idea, whats going on or what is broken?

Please help.

I didn't find the right solution from the Internet.
