  4. Thank you for your video I enjoyed your thoroughness you seem very knowledgeable in network problems. Can you help me out with my issue? We hired a company to build us a website when they tried to point the domain to there server my website went down. I am not able to access from my desktop computer. However, I can access other websites just not our business site. I have tried all settings that have been common to symptoms. I am getting from the cmd( unable to resolve target system name.) I have contacted Comcast which is our local internet provider and they had me do all kinds of cmd prompts to no avail. When I cmd tracert and the website domain it gives me the message up above. I also have a bother who has the same internet provider who lives 12 miles away and he can't access our site as well. Comcast says there are no outages in the system but feel like there has to be a network issue. Can you advise me in anything that might help? Thank you for support.
