Exchange troubleshooting illustration (1)

One question about Exchange: Exchange is installed on the primary domain controller. Due to some problems with the primary domain controller, You need to downgrade. After the primary domain controller is successfully downgraded, although there are many domain numbers on the network, however, the Exchange service cannot be started. Have you ever encountered a similar situation? To be honest, I have never encountered this problem, but I remember that he discussed this issue with me before. I suggested installing another Exchange server for other domains or member servers, in this way, even if the primary domain control is completely deleted, there will be no problems, but at that time, the rice pot opposed this operation, he believes that making a cluster will cause a lot of trouble for future management, and the level of people who raise the problem seems to be poor. cluster management may be difficult for him. From the question raised by mipan, the other party seems to have downgraded the master domain control. It seems that nothing can be done now. Miguo said that his machine is not properly configured and cannot be used as an experiment. He wanted me to help him with the experiment. I thought it would be okay, so I agreed. Now I will write down the entire experiment process, solution, and some detours in the experiment. I hope to share with you.

First, we will introduce the experiment environment:

Domain Name: exc.com

Primary Domain Control

Machine name: TEST2003.exc.com

OS: Windows Server 2003

IP: 192.168.2.1

Subnet Mask: 255.255.2550

DNS server: 192.168.2.1

And install Exchange 2003 on it.

Quota domain control:

Machine name: TEST20031.exc.com

OS: Windows Server 2003

IP: 192.168.2.2

Subnet Mask: 255.255.2550

DNS server: 192.168.2.1

I will not describe how to configure a member server as a primary domain controller, how to configure a domain controller, how to configure DNS, and how to install Exchange 2003, if you have any problems in the configuration and installation process, you can send me E-Mail, my E-Mail: hzswg@sohu.com, this experiment I did a total of two, because it failed for the first time, well, now let's talk about the first experiment:

Of course, first of all, we have to make this environment. I run Dcpromo on the master domain control and downgrade the master domain control to a Member Server:

Click "Next". The following error may occur:

This is because the master domain control is a Global Catalog server. You can click "OK" first, and then go to another domain control to specify the downgrade. You can also go to another domain to specify the downgrade. There is nothing else to say. Just click "Next" along the way. Then restart the system.

After the restart, we found that the Exchang service could not be started, and ran the "System Manager" of Exchange, with the following error:

Then go to the Event Viewer and find that the following error occurs in the system:
