AD查詢4776 登入失敗的電腦 來源工作站錯誤

 在AD查看被鎖定的帳號，用id 4776去撈出登入出敗的訊息，要找出是在哪台電腦做登入行為的。

結果在來源工作站的資訊，是一台沒看到的電腦名稱，也ping不到，覺得很奇怪。

就想到之前遇到來源工作站是空白的問題，那時就繼續在事件檢視器裡去找NTLM的log，可以找到相關的訊息。

這次也想說去NTLM裡面找找，就找到了，在NTLM裡記錄的登入失敗log裡，除了來源工作站，還多了一個安全通道名稱，這邊顯示的才是正確的電腦名稱。

至於為啥來源工作站是一個奇怪的名稱，目前也不知原因。

When checking the locked accounts in Active Directory, I used ID 4776 to retrieve the information about failed logins in order to determine the workstation where the login attempts originated.

The result showed an error in the workstation information, indicating a computer name that I couldn't find or ping, which seemed unusual.

I recalled a previous encounter where the workstation information was blank, so I continued searching for NTLM logs in the Event Viewer, as they often contain relevant details.

This time, I decided to check the NTLM logs and successfully found the failed login log. In addition to the workstation information, there was also a security channel name recorded. The computer name displayed in this section was the correct one.

As for why the workstation information appeared as a strange name, I am currently unaware of the underlying reason.

win7 chrome 播放線上影片 有聲音沒畫面

最近發現在透過chrome看一些線上課程影片時，影片會有聲音沒畫面。

win10的電腦都沒問題，只有win7的電腦會有這種狀況，所以排除影片本身的問題。

後來才發現竟是chrome裡面設定造成的，在win7電腦中，需要把chrome裡面有一個硬體加速的功能關閉，影片的畫面才能正常顯示。

No Video but Sound when Playing Online Videos in Chrome on Windows 7

Recently, I noticed that when using Chrome to watch online course videos, there would be sound but no video playback. This issue was specific to computers running Windows 7, as there were no problems on Windows 10 machines. Therefore, I ruled out any problems with the videos themselves.

Later, I discovered that the issue was actually caused by a setting within Chrome. On the Windows 7 computers, it was necessary to disable a feature called hardware acceleration in Chrome to enable proper video playback.

Teams JavaScript error the specified procedure could no be found

 突然有幾台電腦的teams開啟都會有這個錯誤，無法使用。

重裝teams也沒用。

查了一下，原來是可轉發套件的問題，處理流程如下。

1. 移除teams，並把%appdata%底下teams相關的資料夾全刪除。

2. 移除電腦內所有的visual c++可轉發套件，然後重開機。

3. 安裝最新的2015to2022，visual c++可轉發套件。

4. 安裝teams。

之後就可以正常開啟了。

Teams JavaScript error: "The specified procedure could not be found."

Suddenly, several computers are experiencing this error when opening Teams, rendering it unusable.

Reinstalling Teams did not resolve the issue.

Upon investigation, it was discovered that the problem lies with the redistributable package. The following steps can be taken to address it:

Uninstall Teams and delete all related folders under "%appdata%".

Remove all Visual C++ redistributable packages from the computer and restart.

Install the latest version of the Visual C++ redistributable package (2015 to 2022).

Install Teams.

After following these steps, Teams should open without any errors.

OUTLOOK編輯郵件貼圖沒東西

 outlook在編輯郵件時，要直接把圖貼在內文中，但貼上後，就是空白沒東西。

有時後在郵件的預覽內文視窗，在上下滾動畫面時，畫面也會很頓。

後來有查到，就是WIN10的DPI設定。

就是在解析度的設定上面，還有一個百分比可以調整畫面上字型與項目的大小，如果設定是超過100%，像是125%或150%時，就會造成在編輯郵件時的一些問題，只要調成100%，就可以排除這個怪問題，很奇特的一個問題。

There is nothing in the image pasted in the email while editing it in Outlook.

Sometimes, when scrolling up and down in the preview pane of the Outlook, the screen becomes sluggish. Later, it was found that it is due to the DPI (Dots Per Inch) settings in Windows 10. In the display settings, there is a percentage that can be adjusted to change the size of fonts and items on the screen. If the setting is above 100%, such as 125% or 150%, it can cause issues when editing emails. By adjusting it to 100%, this strange issue can be resolved.
