Naming convention is something that I’m very particular about and one thing that has always bugged me is if hostnames are not the same case. In the Windows world there is no functional difference between upper and lowercase hostname, but it’s still enough to bother me.
To change the case is surprisingly easy.
First we log onto “Active Directory Users and Computers” and enable the “Advanced Features” which lives in the View menu.
Double-click the offending hostname and go to the “Attribute Editor”. Scroll down to the dNSHostName and change the case.
The change will take effect as soon as you reboot the host in question.
