Originally created by @interface-fluidics on GitHub (Feb 26, 2025).

netbird 0.37.1 windows

netbird adds dns suffix to the client, but old network route has been removed as well as no custom dns servers

currently I had to write custom script to that populates my own public dns server in order to just stop those never-ending issues with dns resolving, but because of the dns suffix netbird is trying to use own network dns for the client instead of my public. even if the client in netbirt have been offline for month. manual deleting help, but the fact that netbird adds dns suffix that no longer in the management server is still there.

(0.37 broke all dns resolving with new Networks, including no option to send all traffic to exit node but this is separate cry)
