Problemas no squid "O cache foi incapaz de resolver ..."

[tkd]

Bom dia Amigos,
Estou com problemas no squid ... algumas paginas consigo acessar e outras nao ...
A URL solicitada não pode ser recuperada, ja troquei o dns do arquivo resol.conf e continua a mesma coisa,
poderiam me ajudar por favor ?
Obrigado

--------------------------------------------------------------------------------

Na tentativa de recuperar a URL: http://www.dominio.com.br 

O seguinte erro foi encontrado:

Incapaz de determinar o endereço IP através do nome do host www.dominio.com.br
O servidor DNS retornou:

Server Failure: The name server was unable to process this query.
Isso significa que:

O cache foi incapaz de resolver o nome do host presente na URL.
Verifique se o endereço está correto.
