Don,
DNS info is cached by the following devices within your "Network"
The Hughes Modem (The cure ... remove AC power from the modem for 30 + seconds.)
Your Router (the cure ... ( in part) .. remove AV power from the Router for 30+ seconds)
IF your router is set to get DNS from ISP ... and it doesn't work as you wish .. change it:
Understand that you may have to open a command prompt and run a "ipconfig/ flushdns" to clean out any cached OS DNS info.
If no router, you will have to open each network adaptor .. both wired and wireless and manually change DNS settings.
Router is set to get DNS automatically from ISP, manually setting to Hughes DNS servers changed nothing.
Please note that DHCP and DNS are TWO different things.
You do NOT want to set to Hughes DNS servers if you are having issues.
You DO wish to have YOUR router perform DHCP duties.
DUMP ALL cached data:
Restart in order:
Modem
Router
Computer (then run flush dns command)
Post screenshots.
Don't "give up", Networking has a lot of ... twists, some make sense, some don't.
I followed the order and reset from 'auto from ISP' to the Google servers of 8.8.8.8 and 8.8.4.4. and still get errors.
