IP reserving in DHCP

Hi all,
I would like to know how can we reserve an IP for a particular system whem using DHCP. I have seen in some of my clients where we just sold the hardware. Everytime the system boots it gets the same IP while I believe if we use DHCP it may get any IP.Does it relate to the MAC add or Network Card.If Yes ,so how do we instruct a DHCP server to give it (the client PC)the same IP evrytime it (the client PC)boots.

Thanx in advance.

bye

You will have to exclude the particular address from the DHCP scope and enter it as a static address on the workstation.

For example: set your DHCP scope from 192.168.0.11 to 192.168.0.254. This will leave you with 192.168.0.1 to 192.168.0.10 to use as static addresses.

Yes you can -I am considering NT 4:
There is an Option to add reservatios, you should enter the mac of the Client machine inside the Unique Identifier.
ow to Resolve the MAC?
Simple - PING the Machine and then ARP.

Good Luck
