The DNS server machine currently has no DNS domain name

I found the following message inside the DNS Server Event logs.

What I should do has been explained inside the message but not sure what exactly it means.

Log Name: DNS Server

Source: Microsoft-Windows-DNS-Server-Service

Date: 14.08.2011 11:30:57

Event ID: 414

Task Category: None

Level: Warning

Keywords: Classic

User: N/A

Computer: WIN-EG75FS9C2F2

Description:

The DNS server computer currently does not have a DNS domain name. Its DNS name is a single-label host name with no domain (for example: "host" rather than "host.microsoft.com").

You might have forgotten to configure a primary DNS domain for the server computer.

Because the DNS server has only a single-label name, all zones created will have default records (SOA and NS) created using only this single-label name for the server's host name. This can lead to incorrect and failed referrals when clients and other DNS servers use these records to locate this server by name.

To correct this problem:

1) Click Start, and then click Control Panel.

2) Open System and Maintenance , and then open System.

3) Click Change Settings, and then click Change. 4) Click either Domain or Workgroup, and then type the name of the domain or workgroup you want the computer to join; the domain or workgroup name will be used as your DNS domain name.

5) When prompted, restart the computer.

After the computer restarts, the DNS server will attempt to fix up default records, substituting the new DNS name of this server for the old single-label name. However, you should review the zone's SOA and NS records to ensure that they now use the correct domain name of this server.
