I have what has been a Windows NT domain. My boss has decided that we need to migrate to W2k (not W2k3). This network contains about 20 Win machines at the main location and 4 at a remote site.
The network, which includes Windows PCs as well as Linux servers, uses private IP addr, served by a Linux server (Fedora 9). The DNS Administrator said that DNS is set to accept AD service records.
All of the client PCs are running either W2k Pro or XP Pro. There are only 2 NT machines still in existence. One is the former file server & BDC at the main office. That has been turned off. The other is the BDC running in the remote office.
I have configured a new W2k Svr fileserver and everyone is using it w/o a problem.
I upgraded the PDC from NT to W2k.
A) I want to turn on AD on this domain.
B) I want to promote the new (W2K) fileserver to a DC as soon as I can.
C) I want to promote a W2k Srvr machine in the remote office
D) I want to turn off the final NT machine in the remote office.
When I click on the "Configure your server" option on the W2k Server DC, I get the following msg:
Running the AD install Wizard will demote this server to be a member server or stand alone server depending on what type of domain controller this is. Before you proceed, be sure there are no dependent servers connected to this server.
1) Should I proceed with this? (steps A,B,C& D in that or some other order)
2) If this DC is demoted, do I need to have another DC on the LAN before I do this?
3) I read something about emulation mode and native mode for W2k DCs: that emulation mode is done when there are NT machines (BDCs?) on the network and native when there are not. Does native mode start as soon as the last NT machine is shut down? What are the implications for turning on AD while there is still a remote BCD?
4) Is there a way to verify that AD is actually working?
5) When I want to get AD working on the fileserver and the remote W2k server, do I just do a "dcpromo". Can/should I do this before I get AD running on the former NT/PDC now W2k/DC?
3) That would be the two modes a W2k domain can be running in, "Mixed Mode" and "Native Mode". You can upgrade the AD to "native" as soon as you don't have NT4 *BDCs* anymore (you can still have NT4 *members*).
4) Event log, dcdiag.exe, netdiag.exe.
5) Basically, yes. The second part of the question is n/a
