Flush DNS Button in Controls Bar
Occasionally the Admin/Diagnostics console gets stuck using an IP from old or duplicate DNS entry. According to support running ipconfig /flushdns or removing the duplicate DNS entry will fix this (i have tested and it does solve the issue). So to make things more simple why not have a “Flush DNS” button in the Controls ribbon so there is no need to open a separate command line console. The button should have 2 actions, first to flush the DNS and second to refresh the current list you are viewing.
