win虛擬機無法正常運作 開機出現錯誤 0xC0000017

 今天把一台esxi的虛擬機做還原後，開機出現錯誤，錯誤代碼是0xC0000017，還說什麼系統檔案可能有錯誤，安全模式或回複到上次正常啟動都沒用。

最後就進設定看，發現，記憶體設定只有16m，好小啊，調成16g後，就可以正常開機了，虛驚一場。

Unable to Boot Win Virtual Machine - Error 0xC0000017

Today, after restoring a virtual machine on ESXi, I encountered an error during the boot process. The error code was 0xC0000017, indicating a possible issue with the system files. I tried starting in Safe Mode and even attempted to revert to the last known good configuration, but none of these options resolved the problem.

In a final attempt to troubleshoot, I accessed the settings and discovered that the memory allocation was set to a mere 16MB. It was a surprisingly low value. After adjusting it to 16GB, the virtual machine was able to boot up successfully. It turned out to be a false alarm, and the issue was resolved.

2022年最後一個月選擇權交易

 今年基本上就是慘，前11個月，好像只有一個月是有獲利，其他都賠錢。

12月開始把交易條件訂的比較高，所以交易次數不多，雖然前兩週都只做1口單賣當沖，但至少都有賺，第三週目前確定是沒交易機會了，希望剩下兩週也能順一點，至少讓我最後一個月也是獲利結束今年，把希望寄託在明年。

SQUID Proxy無法連線內部https網站-NONE/503 0 CONNECT

 用SQUID架好Proxy Server後，都蠻順利的，開網站，用LINE，SKYPE等外部的程式都正常。

但要開啟內部的https網站時，就會無法顯示，錯誤訊息會說"網頁可能暫時離線，或是已經遷移到另一個網址"。

在access log裡查到的紀錄都是 "NONE/503 0 CONNECT"。

然後就開始上網到處查，然後有看到有些人提到在squid.conf 裡要加入一行"dns_v4_first on"，雖然感覺這跟我的問題不相關，但就試試吧。

結果在conf裡先搜尋dns的字眼時，看到了這段，"dns_nameservers  8.8.8.8 208.67.222.222"。

DNS居然是指向外部，所以就把內部的DNS SERVER IP加到最前面，重啟服務，就解決這個問題了。

SQUID Proxy Unable to Connect to Internal HTTPS Websites - NONE/503 0 CONNECT

After setting up the SQUID Proxy Server, everything seemed to be working smoothly. Websites loaded fine, and external applications like LINE and Skype functioned properly. However, when trying to access internal HTTPS websites, they would not display, and an error message stating "The webpage might be temporarily down or may have moved to a new address" would appear.

Upon checking the access log, the recorded entries were "NONE/503 0 CONNECT."

I started searching online for a solution and came across a suggestion to add the line "dns_v4_first on" to the squid.conf file. Although it didn't seem directly related to my issue, I decided to give it a try.

While searching for the term "dns" in the configuration file, I came across the following line: "dns_nameservers 8.8.8.8 208.67.222.222."

To my surprise, the DNS servers were pointing to external addresses. So, I added the IP address of the internal DNS server to the beginning of the list, restarted the service, and the problem was resolved.

QNAP TS-432XU(4.3.6)更換故障硬碟

 一台QNAP TS-432XU(4.3.6)有4顆硬碟做RAID5，最後一顆硬碟已出現警告建議更換，雖然還可以用，但這顆硬碟的讀寫速度慢很多，所以影響到一些日常作業。

原本同型號的硬碟停產了，所以就買一個同廠牌同容量，但轉速更快的來換。

雖然知道是熱插拔，但一開始還上網看一下是不是要在管理介面上做什麼操作，後來查到的畫面又跟自己的不同，就決定直接插拔更換了。

插上後系統就自己在重建了，蠻方便的，剩下就讓它跑完重建程序了。

Replacing a Faulty Hard Drive on QNAP TS-432XU(4.3.6)

On a QNAP TS-432XU(4.3.6) device with a RAID 5 configuration using four hard drives, the last drive started showing warning signs and advised replacement. Although it was still functional, its read and write speeds had significantly decreased, affecting daily operations.

Since the original model of the hard drive was no longer available, I purchased a higher-speed drive from the same manufacturer with the same capacity as a replacement.

While I knew that the device supported hot-swapping, I initially checked online to see if there were any specific actions required through the management interface. However, the instructions and screenshots I found were different from what I encountered, so I decided to proceed with a direct replacement.

Once I inserted the new drive, the system automatically initiated the rebuilding process. It was quite convenient, so I allowed it to complete the rebuilding procedure.

QNAP NAS無法發信 Failed to send a test message using SMTP Service.

在QNAP NAS設定好電子郵件設定，用來發送警告信給管理者，設定好後測試，卻都失敗，錯誤訊息就是示"Failed to send a test message using SMTP Service."。

從不同網段連到QNAP的管理web都正常，所以就覺得網路設定都沒問題。

後來就想用ssh連上QNAP，去ping在不同網段的mail server，卻是不通的，然後再執行route -n 顯示路由表時，卻沒有0.0.0.0的路由，這就妙了。

本來想直接用指令去加，但查到的指令route add default gw 192.168.24.1 br0有錯誤，所以就決定回管理web上看看是不是少設了什麼。

結果發現了一個東西，有一個系統預設閘道的設定，之前都沒去理它，後來進去這設定，在把gateway設定上去之後，回到ssh裡，route -n 顯示路由表時，就有0.0.0.0的路由，發送信件的功能也就正常了。

The QNAP NAS is unable to send emails.

When setting up the email configuration on the QNAP NAS to send alert messages to the administrator and testing it, all attempts fail with the error message "Failed to send a test message using SMTP Service."

Since accessing the QNAP management web interface from different networks works fine, it is believed that there are no issues with the network settings.

Later on, an attempt was made to connect to the QNAP using SSH and ping the mail server in a different network segment, but the connection was unsuccessful. Upon executing the command "route -n" to display the routing table, it was noticed that there was no route for 0.0.0.0, which was puzzling.

Initially, there was a plan to manually add the route using the command "route add default gw 192.168.24.1 br0," but it was found to be incorrect. Therefore, the decision was made to go back to the management web interface and check if anything was missing.

As a result, it was discovered that there was a default gateway setting that had been overlooked. Previously, it had not been addressed. After accessing this setting and configuring the gateway, upon returning to the SSH session and executing "route -n" to display the routing table, the route for 0.0.0.0 appeared, and the email sending functionality started working correctly.

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.

7zip 壓縮檔案指令

為了想要定期把一些檔案壓縮成一個檔案，所以就想到要用batch加排程的方式。

7zip有提供相關的指令可以做

指令如下，

7z a d:\backup[%DATE:~0,4%-%DATE:~5,2%-%DATE:~8,2%].7z  @d:\list.txt 

第一欄(7z) - 就是執行程式的名稱，最好是用完整路徑

第二欄(a) - 就是要壓縮的意思

第三欄(d:\xxx) - 就是壓縮檔的名稱，上面的範例是檔名會自動產生當天的日期，後面的副檔名也可以改用zip

第四欄(@:xxx) - @後面要接一個文字檔，這個文字檔裡就列出要壓縮的檔案存放的路徑，所以有3個不同資料夾的檔案要壓在一起，就把三個路徑分三行存在文字檔裡就行了。

以上就是batch檔的內容。

7zip File Compression Command

In order to periodically compress files into a single archive, I decided to use batch scripting along with scheduled tasks. Fortunately, 7zip provides relevant commands to achieve this.

The command is as follows:

7z a d:\backup[%DATE:~0,4%-%DATE:~5,2%-%DATE:~8,2%].7z @d:\list.txt

Here is a breakdown of the command:

The first field (7z) represents the name of the executable program. It is recommended to use the full path to the program.

The second field (a) indicates the action of compressing.

The third field (d:\xxx) specifies the name of the compressed file. In the example above, the file name will be automatically generated based on the current date. You can also change the file extension to .zip if desired.

The fourth field (@:xxx) specifies a text file. This text file contains the paths of the files to be compressed. So, if you have files from three different folders that need to be compressed together, you can list the three paths on separate lines in the text file.

The above instructions can be included in a batch file to automate the process.
