There is no built-in functionality in Windows NT 3.x or 4.0 to automatically perform this task.
However, there may be some situations in which a hardware profile may not accomplish this result (for example, if you have a docking-type laptop computer). When you are in the office, the DHCP-assigned address for the corporate network is bound to the network adapter in the docking station. When you travel to remote corporate sites, you may still want to have the ability to plug the laptop computer into a corporate Ethernet network connection. This requires an additional PC Card network adapter to be installed in the laptop computer. Rather than simply installing the PC Card network adapter, you can install a network adapter and modem combination PC Card. In this case, it may be difficult to configure a hardware profile that eliminates the PC Card network adapter that does not also eliminate the PC Card modem from the profile. In these types of situations, you need to release the DHCP-assigned IP address that is bound to the network adapter instead of eliminating the network adapter as a whole by using a hardware profile.
In Microsoft Windows 95 and Microsoft Windows 98, there is a registry setting that you can use to release the IP address at shutdown. The registry value is named ReleaseLeaseOnShutdown.
