The company intend to upgrade the Win 2k to Win 2K8
I upgrade the AD migration on the workstation, I create the old DNS as a forwarder the DNS record to new Secondary DNS (New DNS record ). The workstation as a DHCP client, the problem is the DHCP don't know which one is new DNS or Old DNS. I don't know how to make the workstation get the new DNS record from Secondary DNS.
Do it any experience system administrator face this problem and resolution?
