Have you installed Internet Explorer 6 SP1, in the affirmative,
uninstall it and go back to IE 5.

Tell me how this works.

Hi wingman_zz,

The chances are, you've installed an MS package on your 2000 computer
which contains a DLL for XP.

Forum:
Subject: [SOLUTION] "RtlDuplicateUnicodeString not found in NTDLL.DLL" error
Newsgroups: microsoft.public.win2000.general

",,,some MS packages... install a DLL named APPHELP.DLL although they
should not. This DLL is XP-specific and should not be installed on
Windows 2000.

If present, the DLL is loaded by these applications. The problem is
that APPHELP.DLL looks for an entry in NTDLL.DLL
(RtlDuplicateUnicodeString) that doesn't exist in Windows 2000.

Just rename (or delete) APPHELP.DLL (it's in SYSTEM32) and you'll get rid of the
error message."

I hope that helps - please let me know how that goes.
