I am currently checking the folder by directly entering the contents of the file server from the client explorer, but if I enter the host name (computer name), I can access without entering credentials However, if you try to enter with an IP address, a screen for entering credentials will be displayed.
I want to prevent my credentials from being displayed.
Thank you.

Network share settings and Guest user controls are in full control.
The IP address is static

    You can see if you start "Credential Manager" from the Windows 10 control panel.
    In explorer credentials, the IP address and server name are treated as different credentials.

    So I think it's better to add something by IP address or prohibit access by IP address.

    I think that it is a good way to add the host name and IP address of the file server to the HOSTS file and access it with the host name.
    If you want to access by IP address for various reasons, try registering the IP address of the file server in the "Local intranet" zone on the [Security] tab in Internet Options of Internet Explorer.
    You may be trying to access at a high security level because it is recognized as an access to the Internet zone if you access it with an IP address even within the corporate network.
    For security reasons, it is recommended to implement a name resolution function (DNS or HOSTS) so that the host name can be accessed as much as possible.
    Unfortunately, the reason why the behavior of file explorer (explorer.exe) is affected by the option setting of Internet Explorer (iexplore.exe) is not known because the document was not found.
