DHCP Client Configuration

Configuring client systems for DHCP is really not much different than what you are used to from Windows NT. In the Network and Dial-up Connections, pick the appropriate network adapter, and access the Internet Protocol (TCP/IP) properties.

A nice feature in Windows 2000 is the fact that changing from DHCP to a static address and vice versa does not require a reboot – which allows you to mess around with settings all you like, minus the frustration element of waiting forever during the boot process.

As with Windows NT 4, you still use the Ipconfig tool from the command prompt to view, renew, and release IP addresses. However, you should also note that Ipconfig has more functionality that in NT 4, and now allows you to reregister in DNS, view and clear your DNS resolver cache, as well as set and show class IDs, as described previously.

The switches available for Ipconfig include:

/? – displays the help message
/all – displays all configuration information
/release – releases IP address from the specified adapter
/renew – renews IP address for the specified adapter
/flushdns – purges the DNS resolver cache
/registerdns – refreshes all DHCP leases and re-registers DNS names
/displaydns – displays the contents of the DNS resolver cache
/showclassid – displays the DHCP class IDs for an adapter
/setclassid – modifies the DHCP class id for an adapter
