** Dica **
Cuidado, ao utilizar essa função, não é confiável para testar Internet. Usavamos em nosso ERP, porém aconteceu de parar nossa emissão de NFe devido a função retornar equivocadamente que não tinha Conexão de Internet na máquina.

Para testar Conexão de Internet recomendo utilizar, o Post do Adriano Boller:
