Adding Second DC running W2K3 Enterprise R2 SP2 to Domain with Existing DC Running W2K3 Standard SP2

Greetings!

We currently have a Domain with a single DC running Windows Server 2003 Standard SP2.  We have added a new server running W2K3 Enterprise R2 SP2 to the Domain, and it is running DNS as a secondary DNS server.

When running DC promo on the Enterprise Server to add it as an additional DC we received the following error: "The Version of the Active Directory Schema of the Source Forest is not compatible with the version of Active Directory on this computer."

Is this error caused because the current DC is not Enterprise, not R2, or both?
Can it be resolved by running adprep /forestprep then adprep /domainprep from the Enterprise R2 CD2?

Thank you in advance!
Doug

You need to run adprep /forestprep and adprep /domainprep from Disc 2 of the R2 media.

Thank you for your response LauraEHunterMVP!

The old DC is in service on the network, and we have folks working 24/7 so there are few times that are "slow" for us to do this.  Is there much risk of service distribution while running adprep?  If memory serves it is pretty benign, but it's been a while since I ran it so I'd appreciate your input.

Thank you again!

Adds some attributes to the schema, updates some permissions within AD, and generates replication traffic in accordance with both. If you're working in a small environment, the replication hit will probably not even be noticeable.

Thank you for all your help so far!

I think the DCPROMO was succesful...I can see all the user, computer, etc. information in Active Directory on the new DC.  My hestitaton is because in the event log there is an error:  Error Event ID 1110 Attempt to determine whether user and machine accounts are in the same forest failed (the interface is unknown)

Any thoughts?

Thank you!
