It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
IIRC, automatic IP addresses have been made illegal. You can, however, still use semi-automatic IP addresses.
In Windows XP if your asking how to change from a static IP to DHCP
Click "Start" --> Click "Run" --> Type "control netconnections"
Right click on the interface you want to configure --> Select "Properties"
In the box for "This connection uses the following items:" select "Internet Protocol (TCP/IP) --> Click "Properties"
Change the setting under the "General" tab to "Obtain an IP address automatically" --> Repeat for DNS server if needed.
