server addresses

DNS server again addresses dont work?
When swich off the computer and restart the DNS settings back to some addresses that are not. If I manually enter the correct address, ie 192. 168. 1. 254, then the work. I tried to "wash DNS window command, but returns saying he is incapable of color. It seems that something prevents the registration of this. Any help would be appreciated. Although I Leave it set to use the DNS server will be preferred, however, even after restarting, but if I can "get the addresses DNS servers automatically "which seems to find addresses that dont work
