velhim me metendo no meio da conversa.
eu tive um problema similar em um cliente e o prob todo era a placa de rede.
outro detalhe tbm que pode ocorrer e o switch qual modelo vc esta usando ? e jah conseguiu ver se tem alguma maquina tagarelando na rede ? da uma olhada no switch e veja se o bixim esta muito frenetico.
esse server que vc esta usando ele esta como all in one ? tipo firewall samba dhcp dns e tudooo mais ?
