Srs,

Esse projeto consegui aqui no VBMANIA, porém ao tentar executar em um PC ele me traz o MAC 000000000000 ao invéz do MAC original como exemplo 00905114EF11... esse PC que necessito rodar essa aplicação o windows esta instalado no D:\windows e essa é a unica diferença q percebi com o PC que estou programando...

Aguardo uma ajuda...

segue o código abaixo
