According to this, Windows 2000 has only limited support for IPv6.



Windows 2000

In March of 2000 (the year the stock market imploded and the dot.com boom
started going bust) Microsoft released something called IPv6 Technology
Preview for Windows 2000. The goal of this release was to provide developers
something to work with to help them write IPv6-aware applications. This
technology preview is still available from the Microsoft Download Center, but
it's not intended for production networks and should be deployed only in a
test environment. So if you're still running Windows 2000 Professional, you
can install this preview to get some limited IPv6 support, which includes
stateless address autoconfiguration (automatic assignment of link-local
addresses to each network interface upon startup) and automatic assignment of
site-local or global addresses when IPv6 router advertisements as received
(requires an IPv6-enabled router). You could try running this on your
production network, but you do so at your own risk since Microsoft doesn't
officially support this version of the IPv6 stack. So again, the best solution
if you want good IPv6 support is to either upgrade to Windows XP now or wait
for Vista.


I have apparently successfully added a sernet-samba-4.4.4-7 as a AD DC to an
existing Win2000 Advanced Server AD DC.  However, that setup runs entirely on

I write 'apparently' because going through the setup per the wiki how to join
a domain as a DC I encountered a couple of errors for which I can obtain no
explanation.  I do not know if these are critical or not so the entire project
(of moving off the existing Win2000 AD DC) is in abeyance until I find out
more.  But, the Samba DC is joined and it does seem to respond as expected.
