DHCP & MAC addresses

?; Does the DHCP service associate IP's to the requesting
NetBIOS name or MAC address? Does it store the MAC
address anywhere that can be reviewed?

Thanks,

Take a look at the address leases in the DHCP snap in.

It associates based on the MAC address (typically provided in the HWADDR
field of the DHCP packet), but can also use the value passed by the client
in the DHCP option 61 Client Identifier (though this is less common).

As mentioned in another reply by Rob Elder (MVP), you can use the snapin to
view the lease records, and see the MAC address/Unique ID that is used. You
can also view this information by using the following Netsh command:
netsh.exe dhcp server <serverIP> scope <scopeID> show clients
