I know that there is a GP to do this with Windows XP, but I
don't
believe there is one for Windows 2000.
See KB article:
http://support.microsoft.com/?kbid=810869
It says that the GP for removing the recycle bin is only
available for
Windows XP (and I'd imagine Server 2003 as well). Personally,
for
Windows 2000 I'd recommend tweakUI. But depending on the
amount of
machines you have, that could be unfeasable.
Sorry I couldn't be more help.
