Hey, Just out of curiosity... anyone know what the following message means? "Valid name, no data record of requested type. The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for. The usual example for this is a host name-to-address translation attempt (using gethostbyname or WSAAsyncGetHostByName) which uses the DNS (Domain Name Server). An MX record is returned but no A record—indicating the host itself exists, but is not directly reachable. " I'm totally lost. I honestly don't know much about network programming and I think this error is beyond what I currently know. Any help would be greatly appreciated! -Ken Noland

DNS is a large, distributed database. This database looks up hierarchical names and maps them to one or more records of different types. Record types may include "A" (for "address"), "CNAME" for name alising, "MX" for mail exchange information, etc.

Thus, the name "mail.somewhere.dom" could exist, but it only contains "MX" and "CNAME" records, not an "A" record. If you then ask for the address for this name, you might get this message back -- there is no "A" record for that name.
