PRB: NSLOOKUP Shows No IP Address for a Domain Name

• Microsoft BackOffice Server version 4.0
• Microsoft BackOffice Small Business Server versions 4.0, 4.0a, 4.5
• Microsoft Windows NT Server version 4.0

SYMPTOMS

When you use NSLOOKUP to get information about a domain name, you only get the domain name back and no IP address.

CAUSE

This problem occurs because there is usually no IP address associated directly to a domain name. IP addresses are usually associated to hosts inside the domain.

RESOLUTION

You can do the following to work around this problem:

Contact the administrator of the DNS server responsible for the domain in question. Ask them to add an "A" record for the domain name to that domain's zone file.

If the DNS server is a computer running Windows NT Server, simply create an "A" record in the appropriate zone, leaving the Host Name edit box empty while providing an appropriate IP address.

You will now see an entry in the zone file with the name of the domain in the (Host) Name column and the specified IP address in the Data column.

At the NSLOOKUP prompt, typing the zone name will now list the IP address along with the domain name.

Example (at the NSLOOKUP Prompt):

>Khalsa.example.microsoft.com

Default Server: MyServer.example.microsoft.com

Address: 10.0.0.2

Name: Khalsa.example.microsoft.com

Address: 192.168.111.1
