Found solution here! Known bug since about 2019: Re: Cannot Change Adapter settings - Microsoft Community Hub
Hello everyone! Hope you're having a lovely day! I'm experiencing a very odd problem with windows server 2019 in a VMWare virtual machine. I can't edit a single important setting. It's very annoying.
My workaround has been to use godmode:
Why does this work, but no other way does? How could I begin to fix it? For a class, we all make virtual machines on virtual networks. This semester we're having this problem that never occured before. Not sure what's goiong on! When I did a fresh install, everything worked. I did some setup on the server and restarted it, and now the problem persists. I didn't have any updates installed except what came on windows server 2019. After experiencing this issue, I enabled updates and installed them all, but the issue persists.
I've verified I should have permissions through all the administration of server settings, group policy, I've installed winaerotweeks and taken ownership of all the relevant files, but nothing has worked. I've done sfc.exe, ran DISM, but I haven't been greeted with success.
