I was in chat with microsoft support for a few hours with no solution. I deleted cookies, temp internet files, download program files, ActiveX controls -- pretty much two hours worth of trial and error. We even did system file checker to completely rebuild windows update. I deleted my installation of Download Accelerator. Windows Update still doesn't load. I have to call back tomorrow for the special "Windows Update Techs." Anybody have an answer? Thanks.
Since it is easier to remember names than numbers, we implemented names. But, computers require numbers to communicate. Thus, DNS translates those names back to the original numbers.
To update DNS means that the DNS tables have been cleared. Thus, when you lookup a name, it has to go out and find the address. This process removes old entries and replaces them with new or updated ones.
