If you want to assign a specific IP address to a specific machine (regardless of hostname), then you need to configure your DHCP server to do that -- usually, it is based on the MAC address of the network card in the client machine. Depending on the DHCP server's capabilities, you can assign an IP address based on the hostname passed to it by the client. Example 1: I was my laptop to always have the IP 172.16.20.35. My PCMCIA card's MAC address is 04:00:A2:36:BA:F0. I need to tell my DHCP server to reserve the IP address 172.16.20.35 for MAC address 04:00:A2:36:BA:F0. In the DHCP server, I can also assign the hostname based on the same MAC address, or I can tell my laptop to use the hostname I want. Example 2: I have a DHCP server that allows me to assign an IP according the the client hostname. In this case, I configure my laptop with a specific hostname, Dedannshae. I tell my DHCP server to reserver the IP address 172.16.20.35 for hostname Dedannshae. When my laptop requests a DHCP configuration, it sends its hostname with the request. Then the DHCP server checks its list of known hostnames, and if it finds a match, it will give my laptop the reserved IP (and any other configuration specifics). There are other issues to be aware of if you really want name resolution to work correctly, but there's plenty of online documentation available. -- Dave Sherman MCSE, MCSA, CCNA "If we wanted you to understand it, we wouldn't call it code."
