Only being basically literate with computer issues, I went and changed DNS server yesterday and was able to read FR but not log on. Everything else worked. Now with the new DNS numbers, I can log on and all else still works. Should I leave things as is or try to backtrack. Would rather leave alone if you recommend.
Put it back the way it was if you saved the info.
