You may not be able to upgrade a Microsoft Windows 2000 Server domain controller to Windows Server 2003 if the Windows 2000 domain controller has the Server for NIS component from Services for UNIX version 2.0 installed. Also, when you try to upgrade to Windows Server 2003, you may be prompted to run Schupgr.exe to upgrade your schema, and when you run this tool, you may receive the following error message:
Schema update failed: attribute in may-contain does not exist.
The upgrade may not work because the attributeSchema 'uid' that is used by Windows 2000 Server for the NIS schema is not compatible with the one that is used by Windows Server 2003.

Important If Services for UNIX version 2.0 has already been removed, this hotfix cannot be installed. In that case, you must run Renameattribute.exe, the attribute renaming program. To rename the attribute without installing the hotfix:
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
The attributeSchema 'uid' is included for RFC 2307 compliance by Server for NIS. However, it is the attributeSchema 'msSFUName' that is actually used in Server for NIS. The fix is to stop copying the msSFUName values to uid, and to rename the attributeSchema 'uid' to 'uid-SFU-V2'. Replication of the schema update to all the peer domain controllers can take some time. Because of this, it is important to wait until the attributeSchema rename process is replicated among all the domain controllers in the forest. The Windows Server 2003 upgrade should complete successfully after the replication completes.
