Also, changing uppercase to lowercase DNS records on Windows DNS is not easy because it is integrated with Active Directory. However, sometimes you may need to change a couple of records from uppercase to lowercase and vice versa to support the vSphere system (Linux is case sensitive).<\/p>\n\n\n\n<p>In this example, I created a DNS hostname record named LinuxVM. Now, I want to change the record to linuxvm. If I delete the DNS record (LinuxVM) and recreate the DNS record (linuxvm), the previous DNS record is still appearing in the DNS record.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"975\" height=\"476\" src=\"https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/image-32.png\" alt=\"\" class=\"wp-image-3952\" srcset=\"https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/image-32.png 975w, https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/image-32-300x146.png 300w, https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/image-32-768x375.png 768w, https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/image-32-200x98.png 200w\" sizes=\"auto, (max-width: 975px) 100vw, 975px\" \/><\/figure>\n\n\n\n<p>Below are a couple of steps that I have used to change the DNS record from uppercase to lowercase.<\/p>\n\n\n\n<p>Step1: Delete the LinuxVM record<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"776\" height=\"411\" src=\"https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/image-38.png\" alt=\"\" class=\"wp-image-3961\" srcset=\"https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/image-38.png 776w, https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/image-38-300x159.png 300w, https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/image-38-768x407.png 768w, https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/image-38-200x106.png 200w\" sizes=\"auto, (max-width: 776px) 100vw, 776px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"957\" height=\"432\" src=\"https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/3-1.jpg\" alt=\"\" class=\"wp-image-3960\" srcset=\"https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/3-1.jpg 957w, https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/3-1-300x135.jpg 300w, https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/3-1-768x347.jpg 768w, https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/3-1-200x90.jpg 200w\" sizes=\"auto, (max-width: 957px) 100vw, 957px\" \/><\/figure>\n\n\n\n<p>Step 2: Delete DNS entry on Active Directory<\/p>\n\n\n\n<p>Open the adsi tool.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"439\" height=\"679\" src=\"https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/image-33.png\" alt=\"\" class=\"wp-image-3954\" srcset=\"https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/image-33.png 439w, https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/image-33-194x300.png 194w, https:\/\/tungle.ca\/wp-content\/uploads\/2022\/06\/image-33-129x200.png 129w\" sizes=\"auto, (max-width: 439px) 100vw, 439px\" \/><\/figure>\n\n\n\n<p>Right-click ADSI Edit &#8211; Connect to.
