..though I hope not after all the time deHakkelaar spent on trying to get me on the right road...and it worked!....but that was 9 month ago.
For various reasons I stopped using Pi-Hole about 9 months ago. It was working perfectly well then. I now want to start using it again. I thought all I had to do was to turn off the DHCP on my router (ASUS AC68U) and away I go....or so I thought!

Welcome back.

From a client that you believe should be connected to the Pi-Hole for DNS, from the command prompt or terminal on that client (and not via ssh or Putty to the Pi), what is the output of
Did you type the command directly into the command prompt on the Windows machine, or were you connected to a ssh session to the Pi at the time and the command was actually run on the Pi?
From the command prompt on the PC, what is the output of this command:
