Mixed vs Native Mode

[Guest]

We have a 2 large NT domains which we are migrating into a new parallel and pristine AD domain
As the migration will be completed a site at a time and all domain controllers going into the new AD domain will be w2k server is there any valid reason not to have the AD domain in native mode?

As long as you don't have any NT4 PDCs or BDCs lingering anywhere on the
network, the switch to native mode shouldn't cause any issues.

Please note, however, that I say "shouldn't", since we've all heard the
occasional story of how the switch broke something critical. If you can
test it (even just setting up a single machine as a "server" and a single
workstation with all of your mission-critical apps) to make sure that
everything will go smoothly, you'll certainly sleep better at night.

Nah, "As long as you don't have any NT4 PDCs or BDCs lingering anywhere on
the
network" You can turn a particular domain into native mode and have several
child domains or other domains within the forest in mixed mode.

Really you don't have a choice. To use ADMT the Win 2k domain must be in
native mode.

thanks for the info, when you say no pdc's or bdc's on the network you are talking about the
AD domain right? Our NT domain would still be in use until all users were

migrated to the new AD domain and so

I understand what you are all saying, but not when you say 'NT domain controllers lingering on the network
we will still have a nt domain with domain controllers on 'the network' (but not in the new domain or forest) until we migrate all users from the NT domain into the new AD domain over a period of maybe a year before decomissioning the nt domain.

If I understand you correctly, you have created a new
domain made entirely of Windows 200 or better domain
controller. You will be migrating users from your NT
domains over to the new domain. If there are no NT4
domain controller in the new domain, then yes, you should
go to native mode. Actually, to use ADMT and migrate the
users, the target domain (new 2000 domain) must be in
native mode. Just realize that once you are in native
mode those domain controllers will no long replicate
information with NT4 domain controllers. According to
your description, this doesn't seem to be a problem and
the native mode switch would be advisable.
