That you could set up a DNS server from the Keep watch over Panel or when selling a member server to a website controller (DC) (Determine A).

Right through the promoting, if a DNS server is just not discovered, you are going to have the choice of putting in it.

To put in a DNS server from the Keep an eye on Panel, practice these steps:

  • From the Begin menu, choose Keep watch over Panel Instruments Supervisor.
  • Extend and click on Roles (Determine B).
  • Make a choice Add Roles and apply the wizard by using deciding on the DNS function (Determine C).
  • Click on Set up to put in DNS in Home windows Server 2008 (Determine D).

DNS console and configuration 
After putting in DNS, one can find the DNS console from Begin Applications Instruments Home windows 2008 offers a wizard to lend a hand configure DNS.

When configuring your DNS server, it’s important to be conversant in the next ideas:

  • Ahead search for zone
  • Reverse search for zone
  • Zone sorts

A ahead look up zone is solely a solution to unravel host names to IP addresses. A reverse look up zone lets in a DNS server to find the DNS title of the host. Principally, it’s the precise reverse of a ahead look up zone. A reverse search for zone will not be required, however it’s straightforward to configure and can enable on your Home windows Server 2008 Server to have full DNS performance.

When choosing a DNS zone kind, you may have the next choices: Energetic Listing (AD) Built-in, Usual Major, and Usual Secondary. AD Built-in retailers the database data in AD and lets in for stable updates to the database file. This choose
ion will seem provided that AD is configured. Whether it is configured and you choose this feature, AD will retailer and replicate your zone information.

A Usual Major zone outlets the database in a textual content file. This newsletter file can also be shared with different DNS servers that retailer their data in a textual content file. At last, a Same old Secondary zone merely creates a replica of the prevailing database from any other DNS server. That is basically used for load balancing.

To open the DNS server configuration software:

  1. Choose DNS from the Administrative Instruments folder to open the DNS console.
  2. Spotlight your pc title and make a selection Motion Click on Subsequent and make a selection to configure the next: ahead look up zone, ahead and reverse search for zone, root guidelines best (Determine E).
  3. Click on Subsequent after which click on Sure to create a ahead search for zone (Determine F).
  4. Make a choice the correct radio button to put in the specified Zone Sort (Determine G).
  5. Click on Subsequent and sort the identify of the zone you might be developing.
  6. Click on Subsequent after which click on Sure to create a reverse look up zone.
  7. Repeat Step 5.
  8. Select whether or not you wish to have an IPv4 or IPv6 Reverse Search for Zone (Determine H).
  9. Click on Subsequent and enter the guidelines to determine the reverse look up zone (Determine I).
  10. That you could select to create a brand new file or use an present DNS file (Determine J).
  11. On the Dynamic Replace window, specify how DNS accepts stable, nonsecure, or no dynamic updates.
  12. If you would like to use a DNS forwarder, which you can follow it on the Forwarders window. (Determine Ok).
  13. Click on End (Determine L).

Managing DNS information 
You’ve now put in and configured your first DNS server, and also you're prepared so as to add data to the zone(s) you created. There are quite a lot of forms of DNS data on hand. A lot of them you’re going to by no means use. We'll be taking a look at these recurrently used DNS information:

  • Begin of Authority (SOA)
  • Identify Servers
  • Host (A)
  • Pointer (PTR)
  • Canonical Identify (CNAME) or Alias
  • Mail Change (MX)

Begin of Authority (SOA) document 
The Start of Authority (SOA) resource record is always first in any standard zone. The Start of Authority (SOA) tab allows you to make any adjustments necessary. You can change the primary server that holds the SOA record, and you can change the person responsible for managing the SOA. Finally, one of the most important features of Windows 2000 is that you can change your DNS server configuration without deleting your zones and having to re-create the wheel (Figure M).

Name Servers 
Name Servers specify all name servers for a particular domain. You set up all primary and secondary name servers through this record.

To create a Name Server, follow these steps:

  1. Select DNS from the Administrative Tools folder to open the DNS console.
  2. Expand the Forward Lookup Zone.
  3. Right-click on the appropriate domain and choose Properties (Figure N).
  4. Select the Name Servers tab and click Add.
  5. Enter the appropriate FQDN Server name and IP address of the DNS server you want to add.

Host (A) records 
A Host (A) record m
aps a host name to an IP address. These records help you easily identify another server in a forward lookup zone. Host records improve query performance in multiple-zone environments, and you can also create a Pointer (PTR) record at the same time. A PTR record resolves an IP address to a host name.

To create a Host record:

  1. Select DNS from the Administrative Tools folder to open the DNS console.
  2. Expand the Forward Lookup Zone and click on the folder representing your domain.
  3. From the Action menu, select New Host.
  4. Enter the Name and IP Address of the host you are creating (Figure O).
  5. Select the Create Associated Pointer (PTR) Record check box if you want to create the PTR record at the same time. Otherwise, you can create it later.
  6. Click the Add Host button.

Pointer (PTR) records 
A Pointer (PTR) record creates the appropriate entry in the reverse lookup zone for reverse queries. As you saw in Figure H, you have the option of creating a PTR record when creating a Host record. If you did not choose to create your PTR record at that time, you can do it at any point.

To create a PTR record:

  1. Select DNS from the Administrative Tools folder to open the DNS console.
  2. Choose the reverse lookup zone where you want your PTR record created.
  3. From the Action menu, select New Pointer (Figure P).
  4. Enter the Host IP Number and Host Name.
  5. Click OK.

Canonical Name (CNAME) or Alias
records
 
A Canonical Name (CNAME) or Alias record allows a DNS server to have multiple names for a single host. For example, an Alias record can have several records that point to a single server in your environment. This is a common approach if you have both your Web server and your mail server running on the same machine.

To create a DNS Alias:

  1. Select DNS from the Administrative Tools folder to open the DNS console.
  2. Expand the Forward Lookup Zone and highlight the folder representing your domain.
  3. From the Action menu, select New Alias.
  4. Enter your Alias Name (Figure Q).
  5. Enter the fully qualified domain name (FQDN).
  6. Click OK.

Mail Exchange (MX) records 
Mail Excha
nge records help you identify mail servers within a zone in your DNS database. With this feature, you can prioritize which mail servers will receive the highest priority. Creating MX records will help you keep track of the location of all of your mail servers.

To create a Mail Exchange (MX) record:

  1. Select DNS from the Administrative Tools folder to open the DNS console.
  2. Expand the Forward Lookup Zone and highlight the folder representing your domain.
  3. From the Action menu, select New Mail Exchanger.
  4. Enter the Host Or Domain (Figure R).
  5. Enter the Mail Server and Mail Server Priority.
  6. Click OK.

Other new records 
You can create
many other types of records. For a complete description, choose Action turn into your highest buddy. This utility is simple to make use of and really versatile. It's a command-line utility that’s integrated inside Home windows 2008. With nslookup, which you can function question trying out of your DNS servers. This knowledge turns out to be useful in troubleshooting title decision issues and debugging different server-associated issues. That you would be able to get right of entry to nslookup (Determine T) proper from the DNS console.
