PeteDotCom -> Networking -> Networking -> DHCP Manager ->   DHCP Manager The DHCP Manager icon is added to the Network Administration Tools group in Program Manager when you set up a Windows NT Server computer to be a DHCP server. You must use DHCP Manager to perform the following basic tasks: Create one or more DHCP scopes to begin providing DHCP services Define properties for the scope, including the lease duration and IP address ranges to be distributed to potential DHCP clients in the scope Define default values for options such as the default gateway, DNS server, or WINS server to be assigned together with an IP address, or add any custom options The procedures for completing these tasks are described in the following sections. To start DHCP Manager From Program Manager, double-click the DHCP Manager icon in the Network Administration group. DHCP Manager window shows the local computer the first time you start DHCP Manager. Subsequently, the window shows a list of the DHCP servers to which DHCP Manager has connected, plus their scopes. The status bar reports the current DHCP Manager activities. Important When you are working with DHCP Manager, all computer names are DNS host names only. The full path specification might be used, such as accounting.trey.com, or a name might be specified relative to the local domain. In the previous example, other computers in the trey.com DNS domain can refer simply to accounting. The DNS host name is not necessarily the same as the NetBIOS computer name used in Windows-based networking. To connect to a DHCP server From the Server menu, choose the Add command to display the Add DHCP Server To Known Server List dialog box. In the DHCP Server box, type the DNS short name or IP address for the DHCP server in which you want to connect, and then choose the OK button. For example, type an address such as 11.1.26.30 or type a DNS name, such as corp01.trey.com, in this box. To disconnect from a selected DHCP server From the Server menu, choose Remove. – Or – Press Del. (Source: http://microsoft.com/, edited by my self)
