When you use Windows Server 2016, you find that you cannot access the "Sysvol" and "Netlogon" two folders of a DC by using an IP address after logging in.
For example, when you access "\\192.168.0.1\Sysvol", you will be prompted to "Access Denied", this time if you enter a domain name can be accessed, such as access to "\\DC\Sysvol" is normal.
Looked up on the internet and said Windows 10 started, the Sysvol and Netlogon shares cannot be accessed by default through a UNC path.
It can be solved by the following methods:
Run "gpedit.msc" to open Group Policy, go to "computer → administrative Templates → network → network provider → Harden UNC path", enable the policy, and then click the "Show" button to enter the server name (for example "\\DC") to "Value name". and enter the following text in the Value field "requiremutualauthentication = 0,requireintegrity = 0,requireprivacy = 0".
Ps:
1. This method should also work with Windows 10
2, I test is only need to enter the server name to "Value name", "value" can be left blank.
