Configuring DNS for Active Directory - MCTS Guide to Microsoft Windows Server 2008 Active Directory Configuration - page 366

3. In the Zone Type window, make sure the Primary zone option button and the Store the zone
in Active Directory check box are selected (the default settings). Click Next .
4. In the Active Directory Zone Replication Scope window, make sure the To all DNS servers
in this domain option button is selected, and then click Next .
5. Type W2k8adXX-External.com in the Zone name text box, and then click Next .
6. In the Dynamic Update window, click the Do not allow dynamic updates option button, and
then click Next . Click Finish .
7. In DNS Manager, click to expand the Forward Lookup Zones folder, if necessary, and then
click to expand the W2k8adXX-External.com folder. Notice there are two records in the
zone file: the SOA record and an NS record.
8. Right-click W2k8adXX-External.com and click New Host (A or AAAA) . Type ServerXX-
Ext in the Name text box (the FQDN is filled in automatically) and 192.168.100.XX in the
IP address text box.
9. Click to clear the Create associated pointer (PTR) record check box and then click the Add
Host button. Click OK to the “successfully created” message, and then click Done .
10. To test your new entry, open a command prompt window, type ping serverXX-Ext.w2k8adXX-
External.com , and press Enter . You should get a successful reply. If not, check your spelling and
syntax in the Ping command and when creating the host record and zone.
11. Type ping serverXX-ext and press Enter . You should get a message that host serverXX-ext
could not be found. This error happens when the domain name isn't included in the name
to look up. In this case, only the default domain name is used (w2k8adXX.com), and there's
no DNS entry for serverXX-Ext in the w2k8adXX.com domain. To solve this problem,
work through the next few steps.
12. Type ipconfig /all | more and press Enter . The first few lines of output are mostly DNS client
configuration information. The Primary Dns Suffix and DNS Suffix Search List lines should
show your domain name. Close the command prompt window.
13. Open the Local Area Connection Properties dialog box. (To do this, open Network and
Sharing Center, click Manage network connections , right-click Local Area Connection , and
click Properties .)
14. Double-click Internet Protocol Version 4 (TCP/IPv4) . In the Properties dialog box, click
Advanced to open the Advanced TCP/IP Settings dialog box, and then click the DNS tab.
15. Click Append these DNS suffixes (in order) . Click Add , and type w2k8adXX-External.com .
Click Add , and then click Add again. Type w2k8adXX.com , and then click Add . Click the
green up arrow to move w2k8adXX.com to the top of the list because it's the domain you'll
be accessing most often. Click OK until the Local Area Connection Properties dialog box is
closed. Close all open windows.
16. Open a command prompt window, type ipconfig /all | more , and press Enter . Notice that
the DNS Suffix Search List reflects the information you just entered in the DNS tab of the
Advanced TCP/IP Settings dialog box. Press the spacebar until you get the command
prompt.
17. Type ping serverXX-Ext and press Enter . You should get a successful reply.
18. Close all open windows and stay logged on for the next activity.
Activity 9-5: Working with Reverse Lookup Zones
Time Required : 15 minutes
Objective : View the properties of reverse lookup zones and create an RLZ.
Description: You're unfamiliar with reverse lookup zones, so you want to explore existing RLZs
on your server to see how they differ from FLZs. You assign a new IP address to your server that
doesn't already have an RLZ associated with it, and then create a new RLZ for the IP address.
