How to Install Exchange in a Child Domain

This article describes how to install Microsoft Exchange in a Microsoft Windows 2000 child domain.

This article assumes that you have already run /Forestprep for the forest and /Domainprep for the child domain. For additional information, click the following article numbers to view the articles in the Microsoft Knowledge Base: To install Exchange in a Windows 2000 child domain, you must use an account that has Exchange Full Administrator permissions for the Exchange organization. For additional information, click the following article number to view the article in the Microsoft Knowledge Base: Note In Microsoft Exchange Server 2003, only Full Adminstrator permissions on the Organization level are required if this is the first server in the child domain. Additional servers in the domain only require Full Administrator permissions on the Administrative Group level.

If an account does not have the appropriate permissions, you must assign the permissions by using the Exchange Delegation Wizard.

To assign Exchange Full Administrator permissions to an account, follow these steps:

1. Log on to a computer that has the Exchange System Manager installed by using an account that is a member of the Exchange Full Administrator role (an account that was specified in /Forestprep).
2. Start the Exchange System Manager.
3. Right-click the Organization container, and then click Delegation Control.
4. Click Next.
5. Click Add, click Browse, and then click the appropriate user or group.
6. Change the role to Exchange Full Administrator.
   
   Note If you want to add multiple users to a specific role, add those users to a group, and then assign the permissions to the group.
7. Click OK, and then click Next.
8. Verify that the changes are correct, and then click Finish.

To install Exchange on a server in a child domain:

1. Log on to the server in the child domain using the account that has been granted the Exchange Full Administrator role for the organization.
2. Run Setup from your Exchange CD-ROM. The Setup.exe file is located in the Setup\i386 folder on the Exchange CD-ROM.

Note If you are joining an existing Exchange site, the account that you use to log on must have the following permissions to access the Exchange Server directory:

• Exchange must recognize the site services account name and password.
• The Exchange Server site naming context for the Exchange Server site you want to join.
• Admin role on the Exchange Server configuration naming context for the Exchange Server site that you want to join.
• A two-way trust is required between the domain where you are installing Exchange and the domain where the Exchange Server computer exists.
