DNS 有不同主機對應相同IP

網域的DNS主機中,發現有一些電腦已取到其他IP,但DNS上還會保留舊記錄,不會自動清除,其他電腦後來取得該IP時,DNS上就有兩台電腦對應同一個IP。

這就會造成連線電腦時,會連錯電腦。

檢查過DHCP,已經設定成動態更新DNS了,還是不會更新DNS記錄,後來查發現,DNS的設定中,也要把啟用動清除過時的記錄打勾,DNS裡的舊記錄才會被清除。



On the domain DNS server, it was found that some computers had already obtained new IP addresses, but the DNS still kept their old records without automatically clearing them. When another computer later obtained that same IP, the DNS ended up showing two computers mapped to the same IP address.

This caused connection issues, as attempts to connect to one computer could actually connect to the wrong one.

After checking the DHCP settings, it was confirmed that dynamic DNS update was already enabled, but the DNS records were still not being updated. Further investigation revealed that in the DNS settings, the option “Enable scavenging of stale records” must also be checked; only then will outdated DNS records be cleared.

synology active backup for business 還原虛擬機 需保持原設定

 synology active backup for business 備份虛擬機後,還原時如果需保持原設定,就需要在還原後,虛擬機第一次開機時,選擇"我已將其移動"。

通常會選這個,是因為裡面有裝一些軟體是會綁定硬體資訊,所以還原時,必須保持所有相關的設定資訊。

pixel6過保送修台灣大哥大

上上週我的 Pixel 6 突然掛掉,重開機後一直卡在「G」的開機畫面。
一開始照網路教學進 fastboot 重置,沒用;接電腦想重灌系統,也失敗。最後只好送去台灣大哥大直營門市。因為已經過保,店員提醒如果不修要收 300 元檢測費。

進度可以在官網查,速度蠻快的。星期三就接到電話,說是主機板壞掉,要換新的,費用 4400,打 9 折後大概 4000。有點貴,加上 Pixel 10 快出了,本來不太想修。沒想到維修人員還問我能接受多少,說可以幫忙爭取,於是我就回說能壓在 3000 以內最好。

後來回覆說最多只能打 8 折,約 3500。雖然還是超過預算,但整個過程人員都很客氣、處理也快,最後我還是決定修。星期五就通知取貨,從星期一送修到星期五拿回來,算是蠻有效率的。

整體感覺:服務態度很好,維修速度也快,感覺很不錯。

outlook傳送接收失敗 出現"未提供"

 outlook突然無法收發信,按下傳送接收時,都會跳出一個"未提供"的錯誤訊息。

重設outlook profile也沒用。

進到控制台,對outlook執行修復就正常了。



Outlook suddenly couldn’t send or receive emails. When clicking Send/Receive, it would always show an error message saying “Not Specified.”

Resetting the Outlook profile didn’t help.

Going into Control Panel and running a repair on Outlook fixed the issue.

手機投影電視 小米電視盒子勝過Terzomen

 

之前為了想把手機畫面直接投影到電視上,買了Terzomen AirLink,快要1900元。

最近又買了小米盒子3,比較一下差別。


Terzomen AirLink

優點:不用特別設定,接上去就可以用了。

缺點:居然只支援apple的產品,android的手機/平板都不支援。

         接在手機那端的連結器看久還蠻燙的。

         單純就是無線傳輸影像的功能,一定要搭配手機或電腦用。

         比較貴。


小米電視盒子3

優點:apple跟android的設備都支援手機投影。

         不需要手機也有一些串流app可以看片。

          比較便宜。

缺點:一開始設定有點難用。

         需要有wifi。




相比之下,配合自己使用的環境,用小米盒子就夠了。

outlook 郵件清單 不要顯示郵件內容

 

outlook 郵件清單,除了寄件人,主旨,時間之類的,還會在下一行顯示部分的郵件內容,

讓整個郵件清單看起來很雜。

可以在檢視的功能表中,在訊息預覽裡面,選擇關閉,就不會顯示那一行郵件內容了。



In the Outlook mail list, in addition to the sender, subject, and time, part of the email content is also displayed on the next line,
which makes the entire mail list look cluttered.

You can go to the View tab and, under Message Preview, select Off to stop showing that line of email content.

M365 outlook 底色亂跳

同一個M365帳號,在兩台電腦上都設定的outlook,但設定的底色不同,結果兩台電腦上的outlook底色都會一直亂跳。

是因為outlook設定,有一個"將我的outlook設定儲存在雲端中"被打勾了,所以兩台電腦的outlook設定會互相影響,只要把這個設定取消就恢復正常了。


The same M365 account was configured in Outlook on two different computers, but each had a different theme color. As a result, the background color in Outlook kept switching back and forth on both computers.

This happened because the Outlook setting "Store my Outlook settings in the cloud" was enabled, causing the settings on one computer to affect the other. Simply unchecking this option resolved the issue.

WINDOWS2019 執行windows update離線安裝檔無反應

 在WINDOWS2019下載windows 的更新檔要進行安裝,但執行後都沒任何反應,或是要等很久才會跳出smart screnn的警告視窗。

這是因為系統設定中,有做安全性控管,設成警告。

只要先把它調成關閉,重新登入一次系統,這時後在點選安裝,視窗就會正常跳出,讓我們點進下一步進行安裝。


When attempting to install Windows updates on Windows Server 2019, nothing happens after execution, or it takes a long time before the SmartScreen warning window appears.

This is due to a security control setting in the system, which is currently set to "Warn."

Simply change the setting to "Off" and log in to the system again. After that, when you click the installer, the window will appear normally, allowing you to proceed with the installation.

excel 沒有任何頁籤

 有一份excel編輯到一半時當掉了,重開啟啟後,裡面完全沒任何東西,沒任何頁籤。

所以就用修復的方式再開啟一次,但還是沒效,想說沒救了。

結果就查了一下excel沒有任何頁籤,沒想到還真的有這個設定,去檢視裡面,取消隱藏頁籤,檔案裡的資料就全部出現,恢復正常了。
