Due to a server crash I need to replace a DHCP server in one of our Sites. I do not have access to the original DHCP server in order to perform a database migration. We have a Server 2003 Domain with five Sites (Each Site has it's own Domain Controller and DHCP Server). The original DHCP server was on a Member Server and the new DHCP Server will be on a Domain Controller. I am familar with configuring a new DHCP server but am wondering about issues arising because existing workstations currently hold address information obtained from the old DHCP Server. Is there a recommended procedure? Thank you.
