Just something interesting I'd like to understand better.

On my windows 10 system (1809)
I have User account control set to the highest level, and I am NOT a local administrator on my system.
When I open a regular command prompt and type "ipconfig /flushdns" it flushes my DNS without issue.

On one of our server 2016 systems where I am Domain Administrator,
We have User account control set to the second to highest level (so less secure than the windows 10 client)
However, if I open up a regular command prompt and type "ipconfig /flushdns" it says:
The requested operation requires elevation.


So why does a domain admin require elevation to flush dns on a server with a lower UAC setting,
when a standard domain user is able to flush dns on a client without local/domain admin and with highest UAC setting?
