Windows is unable to access SMB shares on a NAS when SMB signing is enabled (“RequireSecuritySignature=1”). How can I fix this problem?

SMB signing can be enabled in Windows by setting the registry key “RequireSecuritySignature” to 1. After SMB signing is enabled, Windows is unable to connect to SMB shares on a QNAP NAS.
To work around this problem, open Powershell on the Windows client and run the following command to disable “secure negotiate”:

Set-ItemProperty -Path
"HKLM:\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters" RequireSecureNegotiate -Value 0 –Force
