When you try to resolve a host name using Domain Name Service (DNS), the attempt is unsuccessful. Communication by Internet Protocol (IP) address (even to the DNS server) and the Nslookup utility against the DNS server both work correctly.
The Dynamic Host Configuration Protocol (DHCP) Client Service may not be running.
Start the DHCP Client Service, and then set it to start automatically at startup. To do so, follow these steps:
Right-click the My Computer icon on your desktop, and then click Manage.
In the Computer Management console, double-click Services and Applications, and then click Services.
In the rightmost window, right-click DHCP Client and then click Properties.
Change Startup type to Automatic, and then click OK.
Right-click the DHCP Client service again, and then click Start.
This behavior may occur even if the system is not using DHCP to obtain an IP address; that is, even if the system has a statically configured IP address.
The DHCP Client service is set to start automatically by default in Windows 2000.
The DHCP Client Service is also responsible for registering Dynamic DNS (DDNS) names in Windows 2000.
Important The DHCP client service is required for registration of DNS records computers with DHCP and statically assigned IP addresses.
