Hi everyone
There is a small tip if you ever need to be sure the DNS entry of your server never change, or to be sure they never get scavenged.
If you open your DNS MMC, you will see static entry and dynamic entry that way;
The tip is to show the advanced feature; and after that double-click the record you want to make static, and untick the suppress option; as seen there in french;
After clicking Ok the record will now be tagged static, and will no longer change 🙂
Enjoy the small tip, thanks everyone
