Puoi vedere che ho assegnato un server DNS nella mia configurazione IP, ma PERCHÉ non esegue l'output
*** Can't find server name for address 172.27.0.12: Non-existent domain
*** Default servers are not available
Default Server: Unknown
Che cosa significa dicendo "non disponibile" e sconosciuto ".
Il server DNS (172.27.0.12) funziona correttamente perché risponde alla query di chj.dev.nls come previsto. Il server DNS è un Win2003 SP2.
Alcune informazioni dettagliate:
> set debug
> chj.dev.nls
Server: UnKnown
Address: 172.27.0.12
