Install and configure DHCP server on server 2008 core

start /w ocsetup DHCPServerCore

sc config dhcpserver start= auto

net start dhcpserver

(because the dhcp service will be started automatically from next time)

to authorize dhcp server

netsh dhcp add server servercore.sourav.com 192.168.10.60

to show the dhcp servers on the network

netsh dhcp show server

now we can manage the dhcp server on server 2008 core remotely from a GUI

to do that we have to first restart the server 2008 core (otherwise it didn't work for me at least)

now we can go a different pc,mmc-add remove snap in,dhcp.add server,put the ip of server 2008 core and then you can configure the scope etc...
