     parent servers so that your domain can receive
     queries from other domains.

 Master Zone and Subzones Help          Help 1 of 2
  This screen displays the zones (domains) and
 subzones managed by this master DNS server. If
 this DNS master is managing subnets, you may have
 multiple master zones. If this DNS master is not
 managing subnets, the first domain listed is the
 master zone and each additional domain is a
 subzone managed by this master.
 Each zone consists of a domain or set of domains
 and each domain has one or more database records
 associated with it.

 Master Zone and Subzones Help          Help 2 of 2
  A full domain name can consist of up to 255
 characters. Names for DNS domains are integrated
 into the names of the domains above. At the top
 of the domain is the root and its name is
 represented by a dot or period.  If this DNS
 master is managing subnets, the domain names are
 represented by the subnetwork number.
  From this list, you can do the following:
  <Insert>    Add a zone or subzone.
  <Delete>    Delete a subzone. (You cannot delete
              the master zone.)

 Link Indirect via Forwarders       Help 1 of 1
  Use this form to list servers to act as
 forwarders. These servers speed up the DNS
 query process by forwarding queries to other
 domains.
 This form contains the following fields:
 Forwarder #1
     The IP address of the first designated
     forwarder.
 Forwarder #2
     The IP address of the second designated
     forwarder.
 Forwarder #3
     The IP address of the third designated
     forwarder.
 Replica Databases Help                 Help 1 of 2
  This list displays the domains for which this
 server keeps a read-only copy of the DNS database.
 Updates to the information maintained on the
 master name server automatically propagate to the
 replica databases.
 After you create the DNS replica, this name server
 becomes an authoritative source of DNS information
 for the domain. This redundancy improves the
 stability of the network in case the master
 name server goes down.

  Root Domains Help                                             Page 1 of 1
     "Root Domains" are the highest domains in the domain hierarchy eg. in
     the case of Internet its "." (root), "edu.", "com." etc. Nameservers
     servicing these domains are "all knowing" since they have enough
     information to lead one to any other part of the domain tree. So,
     its very important that your Netware nameserver knows the addresses
     of at least a few of the "root nameservers" so as to have complete
     access over the domain tree. If this information is missing or
     incorrect, the Netware nameserver will work only in a limited way
     i.e. it'll be able to provide information only on the zones for which
     it is authoritative (exported & imported databases) but no information
     on any other part of the domain tree.
     In fact, in this setup, you can list domains from any part of the
     domain tree (not strictly ".") and the nameservers servicing those
     domains.f
 Replica Database Information Help  Help 1 of 2
  This form allows you create and view
 information for a replica DNS database on this
 server. The replica is a read-only copy of the
 master database for the domain you specify.

 hierarchy to receive queries from other
 domains.
 This menu contains the following options:
 Link Direct
     Provide your master name server's IP
     address to the root domain.
 Link Indirect via Forwarders

 Root Domains Help                  Help 1 of 2
  This list displays specific root domains.
 "Root Domains" are the highest domains in the
 domain hierarchy, for example in the Internet
 these domains are "." (root), "edu.", "com.",
 and so forth.
 When you start the DNS server, it is linked
 to the DNS hierarchy and root domains
 automatically.
 Use this list to link to another domain
 directly. This enables queries for the listed
 domain to go directly to a name server
 servicing that domain without the overhead of
 using the root name servers.

  This list displays the subnet partitions for

 service. Use this list to select the
 specific master for which you want to create a
 subzone.
 From this list, you can do the following:
  <Enter>     Select a subnet partition for
              which you want to create a
              subzone.
 Subzones Cannot be Created         Help 1 of 1
  You cannot create a subzone beneath any of
 the available subnets because you cannot use
 the fourth octet to specify a subnet.
 For example, you could create the following
 subzones from the subnets listed below:
 SUBNET              SUBZONE OF THE SUBNET
 130.57.0.0    ----->      130.57.6.0
 130.56.0.0    ----->      130.56.7.0
 However, you cannot create additional subzones
 beneath either of the existing subzones
 because you already used the third octet.
