When you run the Microsoft Exchange Server Setup program on Microsoft Windows NT Server 4.0 Terminal Server Edition after logging on from a local account, you may receive the following error message:

This computer must belong to a Windows NT domain before Microsoft Exchange can be installed.

The computer is already a member of the domain, and it is properly configured to communicate on your local area network.

You may also receive this error message when you use a local account to install Exchange Server on a computer running Microsoft Windows NT Server 4.0.


This behavior can occur when you log on to the computer from a local account instead of a Windows NT domain account.


To resolve this behavior, log off the computer, and then log on again from a Windows NT domain account that has the appropriate permissions to perform installations.
