Hi All,
We are having trouble running dcpromo on a file server to serve as a backup domain controller in our SBS 2003 domain. Here are the steps that we took:
1. Installed DNS (but did not configure) on the backup DC machine
--->the main DNS sever on this machine is the SBS in the LAN properties
2. Ran ADprep on SBS machine - said that it didn't need to be run because it had already been run
3. Attempted to run Adprep on Backup DC - but it failed because it said it wasn't a domain controller
4. Attempted to install the dcpromo, but then got the error message below:

The error message we are receiving is:
The operation failed because:

The Active Directory Installation Wizard cannot continue because the forest is not prepared for installing Windows Server 2003. Use the Adprep command-line tool to prepare both the forest and the domain. For more information about using the Adprep, see Active Directory Help.

"The version of the Active Directory schema of the source forest is not compatible with the version of Active Directory on this computer."

Any help is greatly appreciated!
