outlook 收件都變成純文字格式

 outlook正常的話，收進來的信會是html格式。

如果信突然都變成文字格式，就是設定被調到，改回來就行了，就在信任中心裡有個以純文字讀取所有標準郵件，取消就行了。

Outlook emails are appearing as plain text format.

In a normal Outlook setup, incoming emails are displayed in HTML format.

If suddenly all emails are appearing as plain text, it means that a setting has been changed. To revert back to the original format, follow these steps:

Open Outlook and go to the Trust Center.

Look for the option "Read all standard mail in plain text" within the Trust Center settings.

Uncheck this option to disable plain text reading for all standard emails.

Once you have made this change, Outlook will display emails in their original format again.

Kaspersky Embedded Systems Security 病毒碼更新失敗 Error code: 0x02C2. Subsystem code: 0x4

有兩台裝有Kaspersky Embedded Systems Security3.0的主機病毒碼一直更新失敗，但還有四台都正常。

發信問廠商，回覆是說要做資料庫回溯，但做了也沒用，所以又給了另一個解法，就是升級到3.1。

如果升3.1才有用，那沒道理其他四台用3.0的都沒事啊，所以就覺得廠商的回覆蠻隨便的。

因為是server，也不能隨意重開機，所以就決定把防毒主程式重啟好了。

這版本比較鳥的是，沒有選項讓你直接關閉服務，要去裝kess console，然後裡面才有關閉跟啟用的服務。

重啟後，更新還是失敗，但再一次，就成功了。

原本的錯誤訊息如下

Internal task error occurred. Error code: 0x02C2. Subsystem code: 0x4 (General). For more details go to the Kaspersky Technical Support site: https://click.kaspersky.com/?hl=en-US&link=error&pid=wsee&version=11.0.0.0&error=B4X706X

Kaspersky Embedded Systems Security Virus Database Update Failure Error code: 0x02C2. Subsystem code: 0x4

We encountered issues with two hosts running Kaspersky Embedded Systems Security 3.0, as the virus database updates consistently failed. However, the other four hosts had no problems with the updates.

We reached out to the vendor for assistance, and they suggested performing a database rollback. Unfortunately, this solution did not resolve the issue. They then proposed upgrading to version 3.1 as an alternative resolution.

It seemed odd that only upgrading to 3.1 would solve the problem, considering the other four hosts running 3.0 were functioning fine. We found the vendor's response somewhat casual.

Since these were server systems, we couldn't simply restart them without careful consideration. Instead, we decided to restart the antivirus main service.

One drawback of this version is that it lacks an option to directly disable the service. Instead, we had to install the Kaspersky Endpoint Security for Business console, where we found options to enable and disable services.

After restarting the service, the update initially failed again, but upon a subsequent attempt, it succeeded.

The original error message received was as follows:

"Internal task error occurred. Error code: 0x02C2. Subsystem code: 0x4 (General). For more details, please visit the Kaspersky Technical Support site: https://click.kaspersky.com/?hl=en-US&link=error&pid=wsee&version=11.0.0.0&error=B4X706X"

Fortigate VPN token有時後會沒用

 在fortigate上設定好ad帳號登入vpn，要啟用token驗證，才能連線。

但有些使用者設定好，手機上的程式也啟用了，登入vpn時就不會跳出要輸入token code，就直接登入成功了。

後來才發現是登入帳號大小寫的問題，有的人帳號是用大寫，就不需要輸入token code，用小寫才需要。

後來發現是我們在設定vpn的權限時，一開始是還沒用token時，直接把ad群組加入vpn的設定中。

現在因為要用token，需要把個別的ad帳號加到用戶名單，再加到vpn設定中。

所以vpn的設定裡就會有兩個不同的帳號來源，這時後只要把在vpn設定裡的ad群組拿掉，就行了。

user登入後，就只能接受跟用戶名單裡大小寫都要相符的帳號做登入。

Fortigate VPN Token Sometimes Doesn't Work

When setting up an AD account for VPN login on Fortigate, token authentication needs to be enabled to establish a connection.

However, some users have successfully configured their accounts and activated the token authentication on their mobile devices, but when they log in to the VPN, they are not prompted to enter the token code. Instead, they are logged in directly.

Later, we realized that the issue was related to the case sensitivity of the login credentials. Some users had their usernames in uppercase, which bypassed the need for a token code, while lowercase usernames required it.

We discovered that when initially setting up VPN permissions, before using tokens, we directly added the AD group to the VPN configuration.

Now, with the token requirement, individual AD accounts need to be added to the user list and then included in the VPN configuration.

As a result, the VPN configuration will have two different sources for account information. To resolve this, we simply need to remove the AD group from the VPN configuration.

After this change, users will only be able to log in with usernames that match the case sensitivity specified in the user list.

fortiVPN 使用token登入錯誤 : fortitoken clock drift detected

 結果是安裝fortitoken mobile的手機時間錯誤，把時間調對就好了。

fortiVPN login error with token: fortitoken clock drift detected.

 The issue was caused by incorrect time settings on the mobile device where fortitoken mobile was installed. Simply adjusting the time resolved the problem.

Forti VPN連不上-- 'The server you want to connect to requests identification. Please choose a certificate and try again ( -5)'

 原本很舊的Forti防火牆升級後，有一些人的VPN就無法連線了，本來以為跟client端的vpn程式版本有關，因為公司內有4、5、6、7四種版本。

但後來發現這4個版本也都有不同的使用者可連上VPN，所以不是這個問題。

所以就用就錯誤訊息去查

後來是直接去IE的網際網路選項中，在進階設定裡把TLS1.1跟1.2打勾，就可以解決這個問題了。

Forti VPN cannot connect - 'The server you want to connect to requests identification. Please choose a certificate and try again (-5)'.

After upgrading an outdated Forti firewall, some people were unable to connect to the VPN. Initially, I thought it might be related to different versions of the VPN client software (versions 4, 5, 6, and 7) used within the company.

However, I later discovered that users with all four versions were able to connect to the VPN, so that wasn't the issue.

To troubleshoot, I investigated the error message further.

Eventually, I found that the solution was to go to the Internet Options in Internet Explorer and enable TLS 1.1 and 1.2 in the advanced settings. This resolved the problem.

Fortigate 免費的2個token刪除後無法加回..無法存取forti care

 Fortigate 本身就有含兩個token授權，可以指派其兩個帳號，做雙因子驗證使用。

在測試時，設備本身有簽維護，但版本很舊，在設定時發生一些狀況，後來就把它給刪了，想說應該可以重新加回來，上網找了一下，可以用全都是0的預設設號匯入就行了。

結果~不行，然後有一個按鈕是寫重新下載授權，按下去就跳出無法存取forti care，一整個搞不定。

明明就有維護，還不給我存取，最後就依廠商建議，系統太舊原廠不支援，升級到最新試試，就可以了。

After deleting the two free tokens on FortiGate, I couldn't add them back, and I couldn't access FortiCare.

FortiGate itself comes with two token licenses, allowing for the assignment of two accounts for two-factor authentication purposes.

During testing, the device had an existing maintenance agreement, but it was running on a very outdated version. While configuring it, some issues occurred, so I decided to delete it, thinking that I could add it back later. I searched online and found that I could import a default configuration with all zeros.

However, it didn't work. There was a button labeled "Re-download License," but when I clicked it, it showed an error message saying it couldn't access FortiCare. It was quite frustrating.

Despite having an active maintenance agreement, I was denied access. Finally, following the vendor's suggestion, I upgraded the system to the latest version, and that resolved the issue.

Teams 登入失敗 Error Code caa20002

 突然多位user的Teams登入失敗，錯誤代碼都是caa20002。

這些登入失敗的電腦，都是win7，但又不是每一台win7都有這個問題，有點奇怪。

後來找了幾台不同的電腦測試後，才發現原因。

主要是因為IE的關係，要IE11才能正常登入Teams程式，其他比較低階的版本，都會失敗。

很討厭的問題，因為錯誤訊息根本跟IE沒關係，很難查原因。

Teams Login Failure with Error Code caa20002

Multiple users suddenly encountered login failures in Teams, with the error code caa20002.

Interestingly, these login issues were observed on computers running Windows 7, but not every Windows 7 device was affected, which seemed puzzling.

After conducting tests on several different computers, the root cause was identified.

The problem primarily stemmed from Internet Explorer (IE) compatibility. Teams application requires IE11 to function properly, and lower versions of IE would result in login failures.

This issue was frustrating because the error message provided no indication of an IE-related problem, making it difficult to identify the cause.

Fortigate 內部無法直接連線外部虛擬IP

 在防火牆設定好要對外服務主機的外部IP後。從外部網路連線時，沒問題。

但如果從內部網路去連線這個外部IP，卻是不通的。

原因就出在設定虛擬IP時，有一個欄位"介面"，若沒有指定，就無法從內部做連線。

只要設定好這個虛擬IP所在的介面，就沒問題了。

Fortigate cannot directly connect to an external virtual IP internally.

After configuring the firewall to use an external IP for a specific service host, there is no issue connecting from an external network.

However, if an internal network tries to connect to this external IP, it will not work.

The reason for this lies in the configuration of the virtual IP. There is a field called "Interface" that needs to be specified. Without specifying the interface, internal connections cannot be established.

Once the interface for the virtual IP is properly configured, the issue should be resolved, and internal connections to the external IP will work correctly.

EXCEL開啟出錯 "excel 部分內容有問題 您要我們盡可能嘗試復原嗎"

 有一個有多頁籤的excel檔，裡面只要是文字跟一些圖片。

之前都可以用，今天在開啟時突然跳錯誤

excel自行修復後，檔案可以開，但很多圖片卻不見了，而且每次開啟都會跳一樣的錯誤。

後來有查到一個不錯的解決方法，就是去安裝免費的open office，利用裡面的excel功能來開啟這個異常的檔案，就可以正常開啟了，接著在另存新檔，這個新檔就可以在微軟的excel裡正常執行了。

Excel error on opening: "Excel found unreadable content. Do you want to recover as much as we can?"

There is an Excel file with multiple tabs containing text and some images.

Previously, it was working fine, but today, when trying to open it, an error suddenly occurred.

After Excel attempted to repair the file, it could be opened, but many images were missing, and the same error message appeared every time it was opened.

Later, a helpful solution was found. By installing the free OpenOffice software and using its Excel functionality to open the problematic file, it could be opened successfully. Then, the file was saved as a new file, which could be opened and executed properly in Microsoft Excel.

您的電腦遺失api-ms-win-crt-runtime-l1-1-0-dll

 有些電腦在執行某些程式時，時會出現"您的電腦遺失api-ms-win-crt-runtime-l1-1-0-dll"，以致程式打不開。

重裝程式也沒用，因為這個.dll檔是其他程式提供的，就是微軟的c++可轉發套件。

去下載後重新安裝c++可轉發套件，就可解決此問題。

Your computer is missing api-ms-win-crt-runtime-l1-1-0.dll.

On certain computers, when running certain programs, an error message may appear stating "Your computer is missing api-ms-win-crt-runtime-l1-1-0.dll," causing the program to fail to launch.

Reinstalling the program does not resolve the issue because this .dll file is provided by another program, namely Microsoft's C++ redistributable package.

To resolve this problem, you need to download and reinstall the C++ redistributable package. This will ensure that the missing api-ms-win-crt-runtime-l1-1-0.dll file is properly installed on your computer.

OUTLOOK很舊的信變亂碼 比較新的信正常

因為換新電腦，所以把舊電腦的PST檔一起移到新電腦上。

但 在查詢一些信件時發現一個怪事，大概在2013年以前的信件，全變成亂碼。之後的信件，卻都正常。

在舊電腦上是完成正常的，所以就在找另外兩台電腦來測試，測試後發現，同一個PST檔，在某些電腦上都有這個問題，在另一些電腦卻沒事，跟OUTLOOK或WINDOWS的版本都沒直接關係。

最後才發現，原來是OUTLOOK裡面的編碼設定造成的。

編碼如果改成BIG5，就沒有亂碼的問題，調成UTF8就有。

但還是跟使用者說，因為都是很舊的信才有影響，平常還是建議用UTF8，有需要查舊資料，才用BIG5。

Old emails in Outlook are displayed as garbled characters, while newer emails appear normal. 

Due to a computer upgrade, the PST file from the old computer was transferred to the new computer. However, upon checking some emails, a strange issue was discovered. Emails dated before approximately 2013 appeared as garbled characters, while those after that period appeared correctly.

The emails displayed correctly on the old computer, so additional testing was conducted on two other computers. It was found that the same PST file exhibited this issue on certain computers but not on others, regardless of the version of Outlook or Windows being used. Eventually, it was discovered that the encoding settings within Outlook were causing the problem.

Changing the encoding to BIG5 resolved the issue and prevented the garbled characters. However, it is still recommended to use UTF8 encoding for general use, as it is more widely supported. The BIG5 encoding should be used only when accessing old data that is affected by this issue.

outlook信件有迴紋針，但信裡看不到附件

 偶爾都會有使用者反應，收到的信件，旁邊有迴紋針，表示信中有附件，但信打開，裡面卻只有內文，沒有任何附件。

後來仔細的查詢，當信件進來後，經過第一層的圾垃郵件過濾系統，信還是完整的，附件也都有。

之後進到Mail Server，信也是正常的，然後Outlook收信時，從Mail Server的log上看到，的確也是整封信傳過去，所以就判斷問題是在本機端產生，不是Mail Server的問題。

防毒軟體在安裝時，有另外在Outlook內插入一個增益集程式，做附件掃描的功能，後來在Outlook裡把這個功能關閉，有問題的信在重寄一次，附件就出現了。

Occasionally, users have reported receiving emails with paper clips indicating the presence of attachments, but upon opening the emails, they find only the body text and no attachments.

Upon further investigation, it was found that when the emails arrive, they pass through the initial spam filtering system intact, with all attachments included.

Subsequently, when the emails reach the Mail Server, they are still in their original state. However, while receiving the emails in Outlook, it was observed from the Mail Server logs that the complete emails were indeed being transmitted. This led to the conclusion that the issue originated on the local machine and was not a problem with the Mail Server.

During the installation of the antivirus software, an add-in was inserted into Outlook to enable attachment scanning. However, after disabling this functionality within Outlook, the problematic emails were resent, and the attachments appeared as expected.

Adobe reader開啟檔案錯誤 : 處理註解或連結時出錯。字型指定的編碼(CMap)遺失。

 今天收到一個PDF檔，上面有被加上一些註解，在用最新版的Adobe reader開啟時，就會跳出"處理註解或連結時出錯。字型指定的編碼(CMap)遺失"的錯誤。

內文本身可以看，但註解的部份就無法顯示。

電腦本身除了有裝Adobe reader，也有裝字型包，裡面的註解也都是中文，所以一開始也不知為何會有錯誤。

最後就是把Adobe reader跟字型包重裝，就沒事了。

Error opening file with Adobe Reader: Error processing annotations or links. The specified font encoding (CMap) is missing.

Today I received a PDF file with some annotations added to it. When I tried to open it using the latest version of Adobe Reader, an error message popped up saying, "Error processing annotations or links. The specified font encoding (CMap) is missing."

The main content of the document was visible, but the annotations were not displayed. My computer had Adobe Reader installed, and I had also installed a font package that included Chinese annotations. Therefore, initially, I was unsure why this error occurred.

In the end, I resolved the issue by reinstalling Adobe Reader and the font package, and the problem was fixed.

啟動 office2010 錯誤 0x80070190

 在啟動office時，出現0x80070190的錯誤，這不是序號錯誤，也不用去改機碼。

只要在啟動office的程式時，選擇用"系統管理員身份執行"，開啟程式後在去啟動office授權，就ok了。

When launching Office, an error with the code 0x80070190 appears. This is not a serial number error, and there is no need to modify the registry. To resolve this issue, simply launch the Office program with "Run as administrator" option. Once the program is open, proceed with activating the Office license, and the issue should be resolved.

OCS Inventory NG 2.9.2 很多頁面是空白的

 因為原本的OCS Inventory NG太舊了，agent已不支援最新版的win10，所以要來升級到最新的 2.9.2。

最新的OCS server只能裝在Linux上，所以就選欲centos7來安裝，安裝過程主要是照 https://kifarunix.com/install-and-setup-ocs-ng-inventory-server-on-centos-7/ 這篇來操作。

裝的過程都蠻順利的，agent也要裝到client上了，但最後產生兩個問題。

1. 有抓到client，但軟體清單都是0，這個是因為OCS上有一個整理軟體的程序並不會自動執行，要自己去把這程序設到排程裡，才會統計軟體清單，程序是  /usr/share/ocsinventory-reports/ocsreports/crontab/cron_all_software.php

2. 看到軟體清單後，又發現另一個問題，系統會統計所有軟體被多少電腦安裝的數量，點擊那個次數就可以秀出是哪些電腦，但點擊後卻是空白畫面。

查了兩天，試過升級OCS nightly最新版，OS重裝，關閉SELINUX，都沒用，然後突然發現一篇文章就是在說這個問題，原來是PHP的版本太舊了，只要把PHP的版本升到最新，OCS也不用重裝，網頁畫面就可以正常顯示了。

Due to the outdated version of OCS Inventory NG, the agent no longer supports the latest version of Windows 10. Therefore, it is necessary to upgrade to the latest version, 2.9.2.

The latest OCS server can only be installed on Linux, so CentOS 7 was chosen for the installation process. The installation was primarily performed following the steps outlined in the article: "https://kifarunix.com/install-and-setup-ocs-ng-inventory-server-on-centos-7/".

The installation process went smoothly, and the agent was also installed on the client. However, two issues arose at the end of the process.

The client was detected, but the software inventory showed as 0. This occurred because OCS has a software sorting process that does not execute automatically. To resolve this, it is necessary to manually set up the process in the scheduler. The process is located at "/usr/share/ocsinventory-reports/ocsreports/crontab/cron_all_software.php".

After the software inventory was visible, another issue arose. The system was supposed to track the number of installations of each software on different computers. Clicking on the installation count was expected to display which computers had the software installed, but it resulted in a blank page.

After two days of investigation, attempts were made to upgrade to the latest version of OCS nightly, reinstall the OS, and disable SELINUX, but none of these resolved the issue. Then, by chance, an article was found that addressed this problem. It turned out that the issue was caused by an outdated version of PHP. Upgrading PHP to the latest version resolved the problem, and there was no need to reinstall OCS. The web page now displays correctly.

DELL R740 安裝esxi 6.7 找不到硬碟

在一台新買進來的DELL R740要安裝ESXI6.7時，居然一直找不到內建的硬碟。

已在IDRAC裡確認RAID5的虛擬硬碟已建立了，但在裝ESXI時就是找不到。

後來就上網亂找，發現DELL官網有出ESXI6.7的安裝檔，居然就可以了，實在有點麻煩。

可以在下列網站去下載:

 https://www.dell.com/support/home/zh-tw/drivers/driversdetails?driverid=j75ny

When attempting to install ESXi 6.7 on a newly purchased DELL R740, the internal hard drive couldn't be detected.

I verified in IDRAC that a RAID5 virtual disk had been created, but during the ESXi installation, it remained inaccessible.

Afterwards, I searched online and discovered that DELL's official website offered an ESXi 6.7 installation file, which surprisingly resolved the issue. It was a bit troublesome, though.

You can download it from the following website:

OUTLOOK無法直接開啟PPT附件 另存也不行

 有一台電腦的OUTLOOK在收到PPT的附件時，都無法直接開啟附件，另存後，開啟也會跳錯誤，無法正常操作。

但同一封信在其他電腦上的OUTLOOK都可以正常開啟，所以PPT檔案是沒問題的，那就是個別電腦的問題了。

後來是去POWERPOINT的設定，把受保護的檢視取消就解決了。

On a particular computer, Outlook was unable to directly open PowerPoint attachments. Even after saving them and attempting to open, an error would occur, preventing normal operation.

However, the same email with the PowerPoint attachment could be opened without issues on other computers using Outlook. Therefore, the problem seemed to be specific to that individual computer.

Eventually, the issue was resolved by adjusting the settings in PowerPoint and disabling the protected view.

Forti SSLVPN 程式離線安裝

 Forti防火牆上的sslvpn 連線程式，可以上forti的網站下載。

但下載下來的安裝程式並不是完整的，執行時才會再連上網下載真正的安裝程式到電腦的一個暫存資料夾，載完後才執行安裝，有點浪費時間，而且一定要有網路功能，才能進行安裝。

所以就想找能不能有一個實際的安裝檔，這時就要這麼做

一開始先找一台電腦，照上面的方式，下載最新的安裝程式，執行後會再下載真正的安裝程式，下載好後就會進行安裝，跳出安裝畫面。

這時請到本機的 %LocalAppData%\Temp directory 資料夾中，會看到sslvpn 連線程式的真正安裝檔，檔名會叫"FortiClientVPN...."之類的，蠻好找的，把這個檔案複製出來。

之後其他台電腦要裝，就直接用這個檔案來裝就行了。

Forti SSLVPN program offline install

The SSL VPN client program on the Forti firewall can be downloaded from Forti's website.

However, the downloaded installation program is not complete. It only connects to the internet during execution to download the actual installation files into a temporary folder on the computer. After the files are fully downloaded, the installation process begins. This method is time-consuming and requires an internet connection to complete the installation.

Therefore, the goal is to find an actual installation file. Here's how to do it:

Start by using a computer to download the latest installation program following the aforementioned steps. After executing it, the program will initiate the download of the actual installation files. Once the download is complete, the installation process will begin, and an installation window will appear.

At this point, navigate to the "%LocalAppData%\Temp" directory on your local machine. You will find the actual installation file for the SSL VPN client program there. It will have a filename similar to "FortiClientVPN...." and should be easily identifiable. Simply copy this file.

For installing on other computers, you can directly use this copied file for installation.

重灌win10找不到硬碟

 今天把win10 iso做成安裝usb，重灌的時後，居然在過程中，找不到任何硬碟，換了不同的win10版本也是，這台筆電是這兩年出的，怎麼會這樣。

後來上網查了一下，居然是少了某個驅動，要去下載下來丟到隨身碟裡，重灌時要載入這驅動才看得到硬碟，方法就參考下列網址吧。

https://www.asus.com/tw/support/FAQ/1044458/

when creating a Windows 10 installation USB from an ISO file and attempting to reinstall the operating system, no hard drives were detected during the process. Even after trying different versions of Windows 10, the issue persisted. This laptop was released within the past two years, so it was unexpected.

After conducting an online search, it was discovered that a specific driver was missing. It was necessary to download the driver and save it to a USB drive. During the reinstallation process, the driver needed to be loaded in order to detect the hard drives. For detailed instructions, please refer to the following website:
