SYMPTOMS
When you try to install Exchange Server 2003, Setup may not complete successfully, and you may receive the following error message:

The component &quot;Microsoft Exchange Forest Preparation&quot; cannot be assigned the action &quot;ForestPrep&quot; because: -Setup has encountered an error while trying to contact the Windows Active Directory. The error was: -Failed to connect to the Schema Master server. Please verify that it is up, reachable, and that you have sufficient permissions to use it.

You receive this error message if you run Setup.exe or Update.exe with the /forestprep switch or the /domainprep switch, or if you use the reinstall option or any other option.

If you view the contents of the Exchange Server Setup Progress.log file, you see information that is similar to the following:

[ ] - Setup encountered an error while trying to contact the Windows Active Directory. The error was: - Failed to contact the Schema Master server for this Active Directory forest. -- ID:62082 --

[ ] - The component &quot;Microsoft Exchange Forest Preparation&quot; cannot be assigned the action &quot;ForestPrep&quot; because: - Failed to contact the Schema Master server for this Active Directory forest.



CAUSE
This issue may occur if Setup cannot contact the Schema Master or the other operations master role holders. To confirm that this is the cause of this issue, you can use the Dcdiag tool to verify both of the following:
 * The operations master role holders are known to the domain.
 * The server that assigned this role exists and is accessible.

The following files are available for download from the Microsoft Download Center:

RESOLUTION
To resolve this issue, first try to transfer the operations master role to another domain controller. If that does not work, you can seize the damaged operations master role from the broken domain controller and then transfer it to another domain controller.  Transfer the operations master role to another domain controller.
