Yep Chris was definitely right.
but I think you could still correct your "multiple PDC" problem without
going back too far. I never had this problem myself but here what I'd do:
Because there is no option to "Demote to BDC" in Server Manager you need to
have a BDC around to do the promotion and this way have your PDC demoted. At
the worst case scenario you can take your exchange PDC out to the other
physical network (perhabs a hub) take a PC workstation, build a quick BDC
with same name and IP as your current (new) PDC and promote this PC BDC to
be a PDC on this little network. As a result of this your exchange box will
become a BDC and you may try to plug it back into your real network.
Hope this helps

Hi Pav, I think Chris pointed out the mistake that I made. I should have
left the old PDC running when I promoted the new BDC to a PDC. That might
be the caused of the problem.

Vince,
Did you power your old PDC on being hooked up to the network or not? If you
were plugged in you had 2 PDC on your network at a time. One of these 2
should became a PDC or your network is screwed. Check it in the Server
Manager and demote your old PDC to BDC for sure. Check the Event Viewer on
your exchange box for services that did not start as well to find the
dependancy.
Now I think you could demote your exchange to BDC pretty safely for a couple
of reasons: 1. You can always promote it back if something does't work 2.
Exchange 5.5 doesn't need to run on PDC. Moreover I don't think it is
recommended. You have it like that only because of small Business Server.
Hope this helps
Pav

Hello again,
After getting all the advise (by the way, thanks to all), I decided to
start my upgrade process. I installed 2 new BDC (machine b and c) to my NT4
domain, then shut down my PDC which is also my exchange server. I then
promoted one of the new BDC (machine C) to a PDC, then took it off line and
just stored it. The next step was promoting the other new BDC (machine B)
to a PDC. Everything works so far. So I proceeding turning on my old PDC
(the one with exchange running on it) thinking that I could get exchange
running again and then demote the machine to a BDC. After it started,
Exchange did not start at all. It gave me an Event ID 7001 error for all 5
exchange services.
Event ID: 7001
Source: Service Control Manager

Description:
The Microsoft Exchange Event Service service depends on the Microsoft
Exchange Information Store service which failed to start because of the

I have not demoted this machine so there are 2 PDC. I am afraid to demote
this because I can't really afford to have exchange down. Could having the
2 PDC be the cause of the exchange problem?
Below was my original message.
Thanks again and Happy Thanksgiving everyone.
Vince

Subject: [THIN] OT: NT4 Domain to W2k AD upgrade advise
Hi everyone, I'm taking the leap to active directory finally so I'm trying
to plan out what is the best strategy to approach this task. My network
consist of only one NT4 domain, a PDC (NT4 Small Business Edition with
Exchange) and a BDC (NT4 Server). I also have a few NT4 Servers and a
couple of W2k servers running as member server. I also plan to upgrade my
Exchange 5.5 to 2000. So here is what I am thinking of doing:
1. Because the PDC and BDC are both running in old HP LC3 boxes, I can not
reuse them or upgrade them so I am going to get a couple of new boxes. 2.
Plan to making one of the new box (machine A) a new BDC to the NT4 Domain
3. Promote the new BDC to a PDC 4. Upgrade this new PDC to Win2K DC 5.
Install the 2nd new box (machine B) and make it a Win2K DC and sync with the
other DC 6. Demote machine A from being a DC and then remove it from the
network completely 7. Install fresh W2k server on machine A and make it a
DC, then sync to machine B 8. Install exchange in machine A
Is this the right approach? Do I need to take it off my production network
while doing all the upgrade or can I just do the upgrade on my actual
network since none of my existing server will be touched except for the old
PDC which will have to be taken off line and demote to BDC
Thanks for any advise
Vince
