Configurations of DNS server is a complex process. The configuration demands installation of many parameters manually and thus any of a configuration stages is not automated. We shall describe some the basic moments.

Start DNS Manager from Administrative Tools. At the first start in it there is only one record - Server List which is empty. It is necessary in Server List to add DNS addresses of a server. For this purpose come into dialogue window New Server. In the appeared dialogue window enter the IP-address of your server DNS. It should be the IP-address of a server, instead of its name. DNS will add a server in the list.

DNS breaks your domain into zones, each of which should have a primary server of a zone. This primary server of a zone represents database DNS. Each zone should have also some secondary zone servers, each of which separately cashed a copy of a database, and all together they process inquiries of the client. Such splitting of domains into zones, each of which supports one or several servers, reduce working loading on server DNS and accelerate the answer to inquiries of the user. Secondary servers provide redundancy and balancing of loading.

Reverse lookup zone

Before creation of a zone for your domain it is necessary to organize reverse lookup zone. These zones will transform IP-addresses to names of domains. At addition of records in a domain zone which connect names of domains with IP-addresses, zones of return search can automatically return this communication, that is give a name, associated with each of IP-addresses.

To create reverse lookup zone, two times click the right key of the mouse on the pictogram of server DNS, then choose option New Zone. After the program-expert will open, choose Primary. In the appeared dialogue window enter a name of a zone. You should use the agreement on return search which demands use only first three making TCP/IP addresses. For such network as 192.168.1.0 as a name of a zone use 1.168.192.in-addr.arpa (in-addr.arpa is a special zone in structure DNS, used for performance of return search of addresses by means of the sanction addresses protocol). Press Tab for generation file name for this zone and choose a name by default. Press button "Next". To finish process press button "Finish".

Addition of a primary zone.

Now it is necessary to add a primary zone. Choose option New Zone, press button Primary, and then on Next. Enter a name of a zone and for generation of a file press "Tab". Then press button "Finish".

Further we see, that DNS has automatically added two records to a database - record Start of Authority (SOA) and record Name Server (NS). Record SOA specifies, what computer is the entrusted server of your domain. That is in case of occurrence of inconsistent information DNS will use the data given by this server. For each server of names in a zone there should be record NS.

To use DNS, users of a network should know all how to contact server DNS. It is necessary to configure the client so that it could receive DNS address from server DHCP. For correct work, certainly, it is necessary for you to configure server DHCP with the IP-address of server DNS.

If the configured client is client DHCP it is more anything to do it is not necessary. If you manually appropriate IP-addresses choose Network on Control Panel, and then specify label Protocols. Choose TCP/IP, and then press button Properties then there will be dialogue window TCP/IP Properties. For installation manually addresses of server DNS Server choose label DNS, as shown below.

The organization of switched connections with provider Internet is carried out a little differently. Though your provider will give to you the IP-address, in some cases all of you should configure the switched connection with the IP-address of a server or servers DNS of your Internet service provider. You cannot Sometimes get access to one of resources in Internet that servers of the provider server names of higher levels are disconnected are overloaded or do not work.

If the client whom you configure, should give resources to external users, you should add also a name of the domain in a corresponding dialogue window. This record represents a name of domain Internet. Usually, you can leave this dialogue window empty. After you have finished configuration TCP/IP, reboot the computer.
