Specifies whether the computers to which this setting is applied may attach suffixes to an unqualified multi-label name before sending subsequent DNS queries, if the original name query fails.
A name containing dots, but not dot-terminated, is called an unqualified multi-label name, for example "server.corp". A fully qualified name would have a terminating dot, for example "server.corp.contoso.com.".
If you enable this setting, suffixes are allowed to be appended to an unqualified multi-label name, if the original name query fails. For example, an unqualified multi-label name query for "server.corp" will be queried by the DNS Client first. If the query succeeds, the response is returned to the client. If the query fails, the unqualified multi-label name is appended with DNS Suffixes configured for the computer for queries. These suffixes can be derived from a combination of the local DNS Client's primary domain suffix, a connection-specific domain suffix and/or DNS Suffix Search List.
For example, if the local DNS Client receives a query for "server.corp", and a primary domain suffix is configured as "contoso.com", with this setting the DNS Client will send a query for "server.corp.contoso.com." if the original name query for "server.corp" fails.
If you disable this setting, no suffixes are appended to unqualified multi-label name queries if the original name query fails.
If you do not configure this setting, computers will use their local DNS Client configuration to determine the query behavior for unqualified multi-label names.
