I need to reboot domain A which is windows 2k server because of windows updates, i need domain B which is windows 2003 server to kick in as the backup for the domain and the dhcp scope. my dhcp scope is set as this: domain A has addresses from 10.1.1.1 to 10.1.1. 135 and domain B has addresses 10.1.1.136 to 10.1.1.250 does this matter can i still reboot Domain A and everyone will still have an address. how do i or what are the commands to make domain B the primary so i can reboot server A.
