While trying to connect from the WinPE environment to a NAS you get an error message regarding to the obsolete SMB1 protocol: “You can’t connect to the file share because it is not secure. The share requires the obsolete SMB1 protocol, which is unsafe and could expose your system to attacks. https://go.microsoft.com/fwlink/?linkid=852747.”
The message is caused by the following reason: If a WinPE rescue environment is created on a Windows 10 1709 or newer, the Windows PE also has this version of Windows. Windows 10 1709 no longer supports the obsolete SMB1 protocol. If a NAS uses the SMB1 protocol, it can not be addressed by the WinPE.
The solution may be to set a newer protocol in the NAS, if possible. Please consult your NAS manual.
As mentioned in the Microsoft Support article https://support.microsoft.com/en-us/help/4034314/smbv1-is-not-installed-windows-10-and-windows-server-version-1709: “These devices are not likely running Windows. They are more likely running older versions of Linux, Samba, or other types of third-party software to provide SMB services. Often, these versions of Linux and Samba are, themselves, no longer supported.”
Another possible solution could be to create the rescue environment on an older Windows such as Windows 8.1 or an early Windows 10 (1511, 1607 or probably even 1703).
