Microsoft® Exchange Server 2007 setup cannot continue because the local computer is a domain controller for a child domain.

Exchange 2007 setup will not install on to a domain controller for a child domain unless the domain controller is a global catalog server.

To resolve this issue, promote the domain controller to a global catalog server or install Exchange 2007 to a non-domain controller, a member server, in the child domain, and then rerun the Microsoft Exchange setup.

To correct this warning by making the Exchange server a global catalog server

  1. On the domain controller, click Start, point to Programs, click Administrative Tools, and then click Active Directory Sites and Services.

  2. In the console tree, double-click Sites, double-click the name of the site, and then double-click Servers.

  3. Double-click the target domain controller.

  4. In the results pane, right-click NTDS Settings, and then click Properties.

  5. On the General tab, click to select the Global catalog check box.

  6. Restart the domain controller.
