Windows 10 1709 無法透過網路芳鄰(SMB)存取ASUSTOR NAS
Posted by Jane Tsai on 15 October 2018 02:01 AM
在升級到Windows 10 1709 (RS3) Fall Creators Update以後,原因看起來是Guest access in SMB2 disabled by default,如果您未儲存NAS的帳號密碼至「認證管理員」的話,則會無法連線至NAS的網芳。

In Windows 10 Fall Creators Update and Windows Server version 1709, the SMB2 client no longer allows the following actions:
1. Guest account access to a remote server
2. Fallback to the Guest account after invalid credentials are provided

有問題的情況:
1.使用我的電腦或檔案總管時,連線至 \\NAS\Multimedia,則會出現 0x80004005 錯誤。

2.使用net use \\NAS\Multimedia會出現以下錯誤:
系統發生 1272 錯誤。
您無法存取此共用資料夾,因為您組織的安全性原則已封鎖未經驗證的來賓存取。這些原則可協助保護您的電腦,以防禦網路上不安全或惡意的裝置。
You can't access this shared folder because your organization's security policies block unauthenticated guest access. These policies help protect your PC from unsafe or malicious devices on the network.

解決辦法:
(方法1)把帳號密碼存入認證管理員,認證管理員進入的方式:先按win+r => 輸入control 按enter(也就是選擇「控制台」) => 「使用者帳戶」=>選擇「認證管理員」下面的「管理Windows認證」=>新增Windows認證=>輸入NAS IP或domain name、網芳帳號、網芳密碼=>確定 

(方法2)修改registry,先按win+r => 輸入regedit.msc =>找到 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters] => 修改或新增“AllowInsecureGuestAuth” = 1 (DWORD)
