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:
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.

Version File name
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
- On a domain controller for Active Directory directory
service, log on with administrative credentials.
- Extract the contents of the hotfix. To do this, type the
following command at a command prompt, and then press ENTER:
Q293783_SFU_2_X86.exe /xRenameattribute.exe is extracted to the folder where you placed
the Q293783_SFU_2_X86.exe file.
- Run Renameattribute.exe from the folder where you extracted
it in step 2.
The purpose of this hotfix is to permit you to upgrade from
Windows 2000 to Windows Server 2003. Microsoft has not tested Services for UNIX
2.0 on Windows Server 2003. For more information about interoperability, visit
the following Microsoft Web site:

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.
specifics, see the Hotfix.txt file that is included with the hotfix. Remember
the following information when you install the fix:
- Run the Q293783_sfu_2_x86_en.exe file from its current
location or save it to disk and then run it.
- After the installation, wait for the schema to be
propagated to all the domain controllers that are peers to this domain
controller before you upgrade to Windows Server 2003.
