Windows 7 Máquinas não aceitam endereço IP reservado do DHCP

3

Eu tenho o roteador NETGEAR - WGR614 V6 e tenho uma rede mista de máquinas Linux e Windows. Eu uso o DHCP embutido do roteador. Eu uso o recurso 'Address Reservation' do roteador para reservar IPs com base no endereço MAC. Todas as máquinas Linux obedecem ao servidor DHCP e tomam o IP reservado com satisfação. Os dois PCs com Windows 7, no entanto, nunca aceitam o IP que eu reservei para seus endereços MAC. Eles são inflexíveis quanto ao menor endereço IP disponível na rede e quando eu verifico ipconfig ele diz que é o endereço IP preferido. Agora eu forço o endereço IP em PCs com Windows, iniciando todas as máquinas Linux antes dos PCs com Windows, dessa forma, não tem escolha a não ser aceitar os IPs restantes.

Eu não sei por que o Windows se comporta de maneira estranha, até mesmo meu Nokia e72 e meu kindle obedecem ao servidor DHCP e aceitam o IP que eu quero fornecer a eles.

De acordo com a sua captura do Wireshark, o cliente solicita um endereço várias vezes via DHCP, mas aparentemente não processa a resposta. Se você tiver uma solução de firewall instalada e ativada, desative-a para teste - é bem possível que ela esteja interferindo no processo de atribuição de endereço DHCP.

Qual endereço o cliente obtém no final? Se for 192.168.0.5, o cliente estava mantendo esse endereço muito antes do processo DHCP ser concluído - ele simplesmente mantém o endereço antigo à medida que a solicitação original do DHCP atinge o tempo limite.

Além disso, um pacote DHCP DISCOVER está faltando na captura - ao experimentar com concessões DHCP, por favor, faça um "ciclo completo" emitindo um 

ipconfig /release

seguido por 

ipconfig /renew
