NT 4.0 Server - DNS & WINS Setup
DNS and WINS are tools for handling name resolution. Why we need name resolution? It is
simply to get rid of those meaningless and difficult to remember IP addresses.
DNS is a static dictionary to match host names to IP addresses and vice versa. By
nature, all hosts need to have fix IPs. You might wonder how to provide name resolution
for dynamic IPs from DCHP Servers. In NT's world, we could achieve this by integrating
WINS into DNS since WINS is a dynamic computer name to IP tools. Why we cannot just use
WINS as it is a dynamic tool. The reason is that WINS just provide computer name
resolution but not host name resolution. Host name is in the format of
"hostname.mydomain" while computer name is just "mycomputer". When
integrating WINS into DNS, DNS would use the "mycomputer" as
"hostname" and append "mydomain" at the back.
The followings are the recommended settings and the corresponding sample value.
|Zone Name (Domain Name)
|Reverse Lookup Zone Name
|localhost (A record)
|www (Cname record)
|ftp (Cname record)
- If you follows the procedures in Basic Setup of NT 4.0 Server
in our Technical Notes Collection, skip to step 3. We recommend you read the said procedures if you have not.
- On your NT server, open the Network properties. Select Services Tag and click Add
button. Choose "Microsoft DNS Server" and "Windows Internet Name
Service" then click OK. The system then install the required files from your NT CD
- After the installation, nothing need to do to configure WINS Server.
- Open DNS Manager. Select Options/Preferences and check "Show Automatically Created
Zones" and "Expose TTL" and click OK.
- Select DNS/New Server, and enter server name "nts" then click OK.
- Click on "nts" under server list on the left panel and select DNS/New Zone.
Select Zone Type and Primary and click Next. Enter "ai-net.com.nt" as Zone Name
and press Tab, the system automatically fill up Zone file. Click Next then click Finish.
- Create another zone in the same way as above using Zone Name as
- Click on "ai-net.com.nt" under "nts" on the left panel and select
DNS/Properties. Select WINS lookup Tab and check "Use WINS Resolution" and
"settings only affect local server". Add "192.168.144.1" in WINS
Servers. Click OK.
- Click on "144.168.192.in-addr.arpa" under "nts" on the left panel
and select DNS/Properties. Select WINS Reverse lookup Tab and check "Use WINS Reverse
Resolution" and "settings only affect local server". Type
"ai-net.com.nt" in DNS Host Domain. Click OK.
- Click on "ai-net.com.nt" under "nts" on the left panel and right
click on "nts" on the right panel. Choose delete record. Then click again on
"ai-net.com.nt" under "nts" on the left panel and select DNS/New
Record, choose "A record" in Record Type and select type "nts" and
"192.168.144.1" in Host Name and Host IP Address respectively. Check
"Create Associated PTR Record" and click OK. This step is to create reverse
lookup record for the DNS server "nts" since NT 4.0 has a bug that it would not
automatically create the reverse lookup record when the host record is added during adding
a new server.
- Select DNS/New Record to add one more A record for "localhost" /
- Select DNS/New Record again to add Cname Record. Choose "Cname record" in
Record Type and select type "www" and "nts.ai-net.com.nt." in Alias
Name and For Host DNS Name respectively. Cname record is just like an alias name for an A
record, you can add as much as you like but remember the final "." when you
input for the "For Host DNS Name" field, this is not our typo here.
- Add one more Cname record for "ftp".
- Done, you have your DNS Server integrated with WINS for your domain network.
- To test your name resolution, open DOS prompt and run the following commands
Alternatively, run "nslookup" on your NT Server, type any host name at the
">" prompt like nts, www, ftp, localhost. You can also try any computer name
to see whether it would convert into host name format. To quit "nslookup", type
- ping nts
- ping 192.168.144.1
- ping -a 192.168.144.1
- ping nts.ai-net.com.nt
- ping www
- ping ftp
