I am currently in the process of migrating a 4.0 domain into AD, I have 1 PDC and 1 BDC and another BDC that will be promoted as the AD DC. I also have a 2000 member server installed into the domain, it is running, wins, dns, and dhcp, however the dhcp will not authorize and therfore will acknowledge dhcp requests or send dhcp leases. Does any one know how to make the dhcp be authorized and then give dhcp leases to clients logging into domain ? TIA
