SYMPTOMS

While you are attempting to install Microsoft Exchange Server on a Windows 2000 Server-based computer, you may receive the following error message:

You must be logged into an NT domain to run Microsoft Exchange Server Setup.



This error can also occur if you are installing a new service pack through a terminal server session on a member server in a NT domain.

WORKAROUND

To attempt to work around this behavior:

  • Ensure that you are logged on to the server with a domain account, not a local account.
  • If this does not correct the behavior, check the following registry key:WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
    1. Start Registry Editor (Regedt32.exe).
    2. Locate the DefaultDomainName value under the following key in the registry:

      HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Winlogon

    3. If DefaultDomainName is set to the local computer name, change it to the domain name that the computer account is in, and then try to install Exchange Server again.
    4. Quit Registry Editor.


STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
