My error message states that "Windows could not finish repairing the problem because the following action cannot be completed: Registering with DNS" I have no internet connection on my HP PC, which is why I am typing this on my laptop. On the HP I am running windows xp with sp3. I connect to a cable modem provide by Time Warner. This problem started yesterday, so I have been utilizing both computers with one internet connection, or plugging and unplugging the cat5 cable. I have run Microsoft Essential Full scan, as well as Malwarebytes's Anti-malware. Now I ran both of those in Safe mode, and picked up no bugs. I have Avast as my antivirus software, and the message I receive on that is that "Avast will not be able tp protect mail/news (error 10050). I am unable to turn on the web shields for Avast. I have manually entered the IP addresses into my HP from my laptop, all the way thru DNS servers. It still won't connect. I tried using the Internet explorer diagnostic tool, and it came back and said that I have a winsock issue. It ran thru it's fix, but to no avail. I'm open for any ideas or suggestions to help me alleviate this problem.
