Hello guys, well recently I had this issue too but don’t worry I have got a solution for this freaky problem! - First of all it’s about your router and its configuration, so we have to change it by manual. - go to your router setting and get your “Router configurations” (is this situation I’ll just show stuffs in my version of router {DSL-2740U}) Click on “BackUp Setting” and then download your config.img file- once you got finished with that open your config file with “Notepad++” or whatever you rather and then search for “domain.name” in the config file. - after that, change “domain.name” to something like “domain.local” and save it. - the only thing you have to do now is just update the setting of your router by following the option in your router (as you can see in the picture for me it is under the backup settings and I can choose the config.img file and update the settings by clicking on it) - your router will reboot and update the settings. - it should be done now, just check your windows network setting and check this: as you can see my Primary DNS suffix has been changed to “domain.local” - Hope that I could help, Best regards.
