Win10 system can't access LAN How to solve

It is very common to use computer on LAN, especially for office users. Recently, some users indicated that the Win10 system 9926 preview version could not be used as a normal LAN, resulting in the sharing of resources in the LAN.
In the previous Win10 preview version 9879 or even earlier versions, access to the unshared LAN shared folder all the way, but since the installation or upgrade to Win10 preview version 9926, but can not access the LAN.

I believe most users will choose the toss group policy at this time. , the network sharing center even the registry, to see exactly where the problem, but the actual does not need to be so expensive.



Contact the administrator to set the username and password login mechanism for the LAN server, which can solve the problem of not being able to access the LAN share after upgrading to Win10 Preview Edition 9926.
This problem is caused by Microsoft adding a new security mechanism for Win10, and the existing access form is therefore determined to be unsafe by the system.
