win10专业版系统在加了域之后，共享网络连接缓存无法清空

Question

我当前的电脑系统是windows10专业版，操作系统内部版本是19045.5965。电脑已加入公司的域，且连接过公司内部的共享文件夹。我的问题是我最开始连接共享的时候使用的并非自己的域账号，现在想要清空之前连接共享使用的账号密码的缓存来重新使用自己的域账号密码连接共享，但我发现怎么都清空不了，我的凭据里面已经删除了之前连接的凭据，而且使用net use命令查看也没有任何的连接列表，但我仍然可以直接连到共享里。我不知道还应该在哪里可以清除这些缓存，还是需要在共享文件夹的服务器上进行设置清理。所以请教各位，我应该如何处理？

Dear Team,

Yes, you are encountering a common issue. Even after clearing credentials in Credential Manager and using net use * /delete, Windows 10 can sometimes retain cached network authentication information, especially within a domain environment. This often happens due to Kerberos tickets or other session-based caching.

Here's how to deal with it, in order of increasing impact:

Clear Windows Credentials thoroughly:

• Type "Credential Manager" in the Windows search bar and open it.
  • Go to Windows Credentials.
    • Look for any credentials related to the shared folder's server (e.g., by IP address or hostname) and remove them all. Pay close attention to any entries under "Generic Credentials" or "Network Address".
    Force Close Network Connections and Restart Services:

    - Open Command Prompt as an administrator.
    
       - Type `net use * /delete /y` and press Enter. This will attempt to delete all persistent and current network connections without prompting for confirmation.
    
          - **Crucially, restart the "Workstation" service.** This service handles network connections and restarting it can clear underlying caches. You might need to stop "Netlogon" and "Computer Browser" services first if prompted.
    
                - Open Services (type `services.msc` in Run dialog or search).
    
                      - Find "Workstation" service, right-click, and select "Restart".
    
                            - If prompted, stop and restart "Netlogon" and "Computer Browser" services as well.
    
                               - Close all File Explorer windows.
    

1. Flush DNS Resolver Cache:

• While less directly related to cached credentials, a stale DNS cache can sometimes interfere with how your system resolves the shared server's address and subsequent authentication.
• Open Command Prompt as an administrator.
  • Type ipconfig /flushdns and press Enter.
    • Query successful
