Thanks Polonus.
Is there any difference doing it from the Command prompt,
and just going to network conections and clicking repair?

I know that the DNS flush is one of the functions of repair,
because if you have DNS Client service disabled,you get a failed to flush DNS
message.

I had the service off because of a large host file,and disabling the service was supposed to prevent slow downs.
