We have both the Dell USB-C docks and a couple of the Thunderbolt models. So far we have had no problem with the USB-C. I even use one for my machine. The Thunderbolts were a bit problematic around the first part of 2017, but after several firmware updates they seem to have stabilized.

it should be noted that

it's current build is Microsoft Windows [Version 10.0.17134.112]

it is possible that rolling back (if possible) to 16299.492 would resolve - which at a point - becomes a 'fresh install' as roll back expires.
And since this is a remote system, not convenient to do.

Not often, but my LAN connection goes from my dock to a switch through Powerline adapters to my other main 8-port switch and then to the router. If something fails at any number of points along that way, it's handy to have the failover.

Congrats on intentionally disabling a setting that is designed to make your system work better.
