I have one domain with 2 subdomains. After I ran Forest Prep and Domain Prep, I promo a Windows 2003 SP1 to become a first Windows 2003 Domain Controller. I, then, installed AD Integrated DNS on this server. However, I don't see the ForestDnsZones and DomainDnsZones on this new Windows 2003 DC. I am afraid to go further with the upgrade. Will the missing of these two zones cause any problems when I try to promo other Windows 2003 servers to become a DCs or upgrade other Windows 2000 DC to Windows 2003 DC? I could see all the ForestUpdate and DomainUpgrade when I ran the ADSIEdit app. There is no error in the eventvwr log on any of DC. There is also no replication error.
