Specifies that [removed: computers][added: the DNS client] 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" is an unqualified multi-label name. The name "server.corp.contoso.com." is an example of a fully qualified name because it contains a terminating dot. For example, if attaching suffixes is allowed, 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. These suffixes can be derived from a combination of the local DNS client's primary domain suffix, a connection-specific domain suffix, and a DNS suffix search list. If attaching suffixes is allowed, and a DNS client with a primary domain suffix of "contoso.com" performs a query for "server.corp" the DNS client will send a query for "server.corp" first, and then a query for "server.corp.contoso.com." second if the first query fails. If you enable this policy setting, suffixes are allowed to be appended to an unqualified multi-label name if the original name query fails. If you disable this policy setting, no suffixes are appended to unqualified multi-label name queries if the original name query fails. If you do not configure this policy setting, [removed: computers][added: the DNS client] will use [removed: their][added: its] local[removed: DNS client] settings to determine the query behavior for unqualified multi-label names.

Specifies a connection-specific DNS suffix. This policy setting supersedes local connection-specific DNS suffixes, and those configured using DHCP. To use this policy setting, click Enabled, and then enter a string value representing the DNS suffix. If you enable this policy setting, the DNS suffix that you enter will be applied to all network connections used by [removed: computers that receive this policy setting.][added: the DNS client.] If you disable this policy setting, or if you do not configure this policy setting, [removed: computers][added: the DNS client] will use the local or DHCP supplied connection specific DNS suffix, if configured.

Specifies if the devolution level that DNS clients will use if they perform primary DNS suffix devolution during the name resolution process. With devolution, a DNS client creates queries by appending a single-label, unqualified domain name with the parent suffix of the primary DNS suffix name, and the parent of that suffix, and so on, stopping if the name is successfully resolved or at a level determined by devolution settings. Devolution can be used when a user or application submits a query for a single-label domain name. The DNS client appends DNS suffixes to the single-label, unqualified domain name based on the state of the Append primary and connection specific DNS suffixes radio button and Append parent suffixes of the primary DNS suffix check box on the DNS tab in Advanced TCP/IP Settings for the Internet Protocol (TCP/IP) Properties dialog box. Devolution is not enabled if a global suffix search list is configured using Group Policy. If a global suffix search list is not configured, and the Append primary and connection specific DNS suffixes radio button is selected, the DNS client appends the following names to a single-label name when it sends DNS queries: The primary DNS suffix, as specified on the Computer Name tab of the System control panel. Each connection-specific DNS suffix, assigned either through DHCP or specified in the DNS suffix for this connection box on the DNS tab in the Advanced TCP/IP Settings dialog box for each connection. For example, when a user submits a query for a single-label name such as "example," the DNS client attaches a suffix such as "microsoft.com" resulting in the query "example.microsoft.com," before sending the query to a DNS server. If a DNS suffix search list is not specified, the DNS client attaches the primary DNS suffix to a single-label name. If this query fails, the connection-specific DNS suffix is attached for a new query. If none of these queries are resolved, the client devolves the primary DNS suffix of the [removed: computer][added: DNS client] (drops the leftmost label of the primary DNS suffix), attaches this devolved primary DNS suffix to the single-label name, and submits this new query to a DNS server. For example, if the primary DNS suffix ooo.aaa.microsoft.com is attached to the non-dot-terminated single-label name "example," and the DNS query for example.ooo.aaa.microsoft.com fails, the DNS client devolves the primary DNS suffix (drops the leftmost label) till the specified devolution level, and submits a query for example.aaa.microsoft.com. If this query fails, the primary DNS suffix is devolved further if it is under specified devolution level and the query example.microsoft.com is submitted. If this query fails, devolution continues if it is under specified devolution level and the query example.microsoft.com is submitted, corresponding to a devolution level of two. The primary DNS suffix cannot be devolved beyond a devolution level of two. The devolution level can be configured using this policy setting. The default devolution level is two. If you enable this policy setting and DNS devolution is also enabled, DNS clients use the DNS devolution level that you specify. If this policy setting is disabled, or if this policy setting is not configured, DNS clients use the default devolution level of two provided that DNS devolution is enabled.

Specifies whether the DNS client should convert internationalized domain names (IDNs) to Punycode when the [removed: computer][added: DNS client] is on non-domain networks with no WINS servers configured. If this policy setting is enabled, IDNs are not converted to Punycode. If this policy setting is disabled, or if this policy setting is not configured, IDNs are converted to Punycode when the [removed: computer][added: DNS client] is on non-domain networks with no WINS servers configured.

Defines the DNS servers to which [removed: a computer][added: the DNS client] sends queries when it attempts to resolve names. This policy setting supersedes the list of DNS servers configured locally and those configured using DHCP. To use this policy setting, click Enabled, and then enter a space-delimited list of IP addresses in the available field. To use this policy setting, you must enter at least one IP address. If you enable this policy setting, the list of DNS servers is applied to all network connections used by [removed: computers that receive this policy setting.][added: the DNS client.] If you disable this policy setting, or if you do not configure this policy setting, [removed: computers][added: the DNS client] will use the local or DHCP supplied list of DNS servers, if configured.
