And how do I resolve this?  Thanks

Hello Ed,

What that message usually means is that you clicked Cancel on one of the previous configuration screens.

What happen first is you got an error about being unable to connect to the system database, then there would have been a configuration dialog and anywhere after that, clicking Cancel will give the "Unable to create name resolvers" message.

Seeing this is 2021.1, which means this has been working for a while, the most likely answer would be to start the engine on the Server or poke the holes on you need your newly activated firewall, but it could be other things as well. See How to troubleshoot System Database Connection Error for complete troubleshooting steps.
