    A clip from the article:
    Raise the Forest Functional Level
    CAUTION: Do not raise the forest functional level if you have, or will have, any domain controllers running Windows NT 4.0 or Windows 2000. As soon as the forest functional level is raised to Windows Server 2003, it cannot be changed back to the Windows 2000 forest functional level.
    Log on to the PDC of the forest root domain with a user account that is a member of the Enterprise Administrators group.
    Open Active Directory Domains and Trusts, click Start, point to All Programs, point to Administrative Tools, and then click Active Directory Domains and Trusts.
    In the console tree, right-click Active Directory Domains and Trusts, and then click Raise Forest Functional Level.
    Under Select an available forest functional level, click Windows Server 2003, and then click Raise.

    Note To raise the forest functional level, you must upgrade (or demote) all existing Windows 2000 domain controllers in your forest.

    If you cannot raise the forest functional level, you can click Save As in the Raise Forest Functional Level dialog box to save a log file that specifies which domain controllers in the forest still must be upgraded from Windows NT 4.0 or Windows 2000.

    If you receive a message that indicates you cannot raise the forest functional level, use the report generated by "Save As" to identify all domains and domain controllers that do not meet the requirements for the requested increase.

    The current forest functional level appears under Current forest functional level in the Raise Forest Functional Level dialog box. After the forest level is successfully increased and replicated to the PDCs in the domains, the PDCs for each domain automatically increase their domain level to the current forest level. The level increase is performed on the Schema FSMO and requires Enterprise Administrator credentials.
