WhenWindows 11 24H2was first releasedin theInsiderchannels, most of us focused on AI integration and features likeWindows RecallandAI Explorer. But as we got more insights into the security-related upgrades, it became apparent that drive mapping onWindows 11 24H2is set to undergo a major change!

Depending on whether the configuration conflict lies with theSMBsigningrequirement orGuest fallback, you can encounter a host of different errors. Common ones includeSTATUS_INVALID_SIGNATURE,The cryptographic signature is invalid,0x80070035 The network path wasnot found, orSystem error 3227320323 has occurred, according to Microsoft.
Microsoft’s recommended solutions for drive mapping errors in Windows 11 24H2
Microsoft suggests that you verify whether the NAS supportsSMBand enable it via the management software. Similarly, disableGuest Accessand add a username and password in your NAS. The steps for all three should be available on the manufacturer’s official website.
If that’s not a possibility, Microsoft recommends installing any available firmware updates or replacing the NAS altogether. Because that’s the secure way!
However, if you are willing to take the risk, there’s a way to disable SMB client signing and guest fallback protection (not recommended), according to Microsoft.
