3.5. Changing the Forest Functional Level
You want to change the mode of operation for your Windows 2003 forest from mixed mode to native mode so that you can create forest trusts to improve interoperability between two separate Exchange organizations.
Solution
Using a graphical user interface
Go to Start→ Administrative Tools and select Active Directory Domains and Trusts.
In the left pane, right-click Active Directory Domains and Trusts and select the Raise Forest Functional Level command. You won't see it if the forest functional level has already been raised.
Select Windows Server 2003 Functional Level and click OK.
Click OK to acknowledge the dialog box.
Using a command-line interface
To retrieve the current forest functional level, use the following command:
> dsquery * <ForestRootDN> -scope base -attr msDS-Behavior-VersionOr you can use the enumprop
command found in the Windows 2000 Resource Kit:
> enumprop /ATTR:msDS-Behavior-Version "LDAP://<ForestRootDN>"To change the functional level to Windows Server 2003, use Notepad to create an LDIF file called raise_forest_func_level.ldf with the following contents:
dn: cn=partitions,cn=configuration,<ForestRootDN>
changetype: modify
replace: msDS-Behavior-Version
msDS-Behavior-Version: 2

command to import the change.
> ldifde -I -f raise_forest_func_level.ldf
