. Lists the available IP addresses for master servers that can be contacted to obtain updated records information about this zone. This box only appears if the zone type is set to secondary on this DNS server. When the secondary zone file used locally on this computer expires, the DNS server uses this list to contact a master server for a zone update. If the zone has changed and an update is needed, either a partial or full transfer of the zone is made. The list is in priority order for making contacts.


Provides a space for you to type an IP address for other DNS servers that will be used as master servers for this zone. This box is only active if the zone type is set to secondary for this DNS server. Master servers are used to source and update information about the zone to servers hosting a secondary copy of the zone. Where more than one server appears in the list and a zone update is requested, the list of master servers are used and prioritized by the order in which they appear in the list.


Displays the minimum default Time-To-Live (TTL) interval, supplied along with the data by a DNS name server when it responds to a DNS query. The TTL interval indicates how long the receiving name server is allowed to cache the data from the query. When you create a new DNS zone, the default value is 60 minutes.


Select the type of name checking used for this zone. Changing this value might result in changes to the data in your zone. For more information, see Checking names and zone data.

Provides a space for you to type the fully qualified domain name (FQDN) of the target host that provides the type of TCP/IP-based service described in Service. The name here must match a valid host (A) resource record in the DNS domain namespace. If a target FQDN consisting of a single period (".") is used here, it indicates to any DNS resolvers (clients) requesting this type of service that this service is not available for this domain. For more information, see Resource Records reference: SRV.


Specifies whether the DNS server parses and submits DNS name queries to WINS for resolution. Use this option only if you are currently using NetBIOS Scope in your Windows 2000 network.

When this option is selected, the host name is submitted as the NetBIOS computer name, and the domain name is submitted as the NetBIOS Scope identifier.

Use of NetBIOS Scope is strongly discouraged if you are not already using it on your network. Use NetBIOS Scope only when it is necessary to isolate NetBIOS services (such as net logon and domain controller pass-through authentication) for a group of legacy NetBIOS computers that must not be allowed to communicate with other legacy NetBIOS computers on your private network. For more information about NetBIOS Scope, see the Windows 2000 Server Resource Kit Networking Guide.


Specifies whether the DNS server replicates any WINS-specific resource record data it uses to other DNS servers during zone transfers. Selecting this option can be useful in preventing zone update failures or zone data errors when you are using a combination of Microsoft and other DNS servers on your network to load the zone.


Lists name servers (NS) configured for either the server or zone as follows:

•	When viewed from the Root Hints tab, located under applicable DNS server Properties, this displays a root hints list containing suggested root servers for the server to use and refer to in resolving names. For root servers, this field should be blank. For more information, see Updating root hints.

•	When viewed from the Name Servers tab, located under applicable zone Properties, this displays the a list of DNS servers currently configured to be authoritative for the zone. In most cases, this includes all other servers that are configured as zone secondaries. For more information, see The NS resource record.


Provides a space for you to type text describing the operating system for this host. This field is optional.


Specifies that the host computer in Server name is a custom subtype. If you select this option, you must enter a custom subtype value for this record.

Displays the TCP/IP server port on the host that offers the service specified in Service on the target host specified in Host offering this service. The range of port numbers is 0-65535. This number is often, but not required to be, a well known reserved port number as specified in RFC 1700, "Assigned Numbers". Depending on which Protocol was included in this record, the port number used here can represent either a UDP or TCP port.


Provides a space for you to type a number between 0 and 65535 that indicates the mail exchange server’s priority with respect to the other mail exchange servers. Lower numbers are given preference to servers referenced in MX resource records with higher priority numbers. The highest priority or preference for a mail exchange server is granted when a value of zero (0) is used.

Where more than one MX resource record is present, the mailer attempts delivery to the mail exchange server with the lowest preference number first. If delivery fails, the mail exchange server with the next highest preference number is tried.

If two or more mail exchange servers share the same preference number, the mailer tries one of like number randomly.


Provides a space for you to type a number from 0 to 65535 that specifies the preference given to this resource record among others at the same owner. Lower values are recommended.


Select the available update policy options that determine how this zone handles DNS dynamic updates:

•	For Standard primary zones, you can choose to enable or disable all updates.

•	For Active Directory integrated zones, you have the additional option of selecting to allow only secure updates.

For more information, see Dynamic update.


Provides a space for you to type the host name for the DNS server that is designated as the primary master for this zone. Click Browse to search the DNS namespace for other servers if necessary.


Provides a space for you to type a number between 0 and 65535, indicating the priority or level of preference given to the host specified in Host offering this service for this record.

This number is used to indicate this host’s priority with respect to the other hosts in this domain that offer the same service and are specified by different service location (SRV) resource records. Lower numbers are given higher preference. The highest priority or preference goes to a host (offering the service specified in this record) that has a priority value of zero (0).

Where more than one SRV resource record is present for a specific service, the host with the lowest preference number is given first to DNS clients. If this host fails or is not reachable, the SRV specified host with the next highest preference number is the next host used.

If two or more hosts listed in the SRV resource record for a specified service share the same preference number, DNS clients can try hosts of equal preference in random order.


Provides a space for you to type or select the transport protocol used by this service. In most cases, TCP and UDP are the most useful values. Other transport protocols that have been assigned a symbolic protocol name (as defined in RFC 1700, "Assigned Numbers") can be specified for new transport protocol services, such as RTP, if they are implemented for your network.

Provides a space for you to select or type an interval of time, in either days or hours. When automatic scavenging is enabled at the server, this period represents the time between repetitions of the automated scavenging process. The default value for this is 7 days. To prevent deterioration of DNS server performance, the minimum allowed value for this is 1 hour.


Provides a space for you to select or type an interval of time, in either days or hours. After the no-refresh interval expires, resource records are expected to remain in the DNS database for at least the period of time specified here.

When configured for server properties, this value applies as the default value for all zones. When configured at a specific zone, this value applies only to that zone.

This interval should not be smaller than the maximum refresh period for any resource records. In most networks, this interval corresponds to the DHCP lease renew interval. For Windows 2000 DHCP servers, the default renew interval is four days.


Provides a space for you to select or type an interval of time, in either days or hours. When a resource record is refreshed, it is not refreshed again until this interval of time has elapsed.

When configured for server properties, this value applies as the default value for all zones. When configured at a specific zone, this value applies only to that zone.

If this interval is increased, it can cause stale resource records to remain in the DNS database for a longer period of time.

When selecting among more than one target SRV host for the type of service (specified in Service) that use the same Priority number, this field can be used to weight preference towards specific hosts. Where several hosts share equal priority, SRV-specified hosts with higher weight values entered here should be returned first to resolver clients in SRV query results.

It is recommended that DNS administrators use a value of 0 (no weighting) here when load balancing is not needed. This reduces processing time for SRV queries and makes SRV resource records more readable.


Provides a space for you to type the Public Switched Data Network (PSDN) address used for X.25 connection with the host (a computer or other network device) specified in Record or the parent DNS domain specified in Parent domain for this resource record. X.25 PSDN numbers used here should follow the X.121 numbering plan. X.121 is an X.25 addressing standard established by the International Standards Organization (ISO) and specifies a format for public X.25 network addresses that is internationally accepted.
