Why is Teamviewer asking for my network's Domain username and password to reboot a server?

Options

I first click reboot at top

Then click reboot again

Then this box pops up in bottom right. It's not looking for my TeamViewer password its looking for the password to the local administrator account of the machine or domain admin account in order to restart the machine. This never used to ask this and is very inconvenient if Windows is locked up in some manner. Anyway to disable this feature? Is it new?
