SYMPTOMS
When you try to run BackOffice Server 2000 or Small Business Server (SBS) 2000 Setup to upgrade a computer that is running a earlier version of this software with Microsoft Exchange Server 5.5, you may receive the following &quot;hard block&quot; message in the Suite Requirements window:

Exchange Internet Mail Connector Installed



CAUSE
This problem can occur in either of the following scenarios:  The Internet Mail Service is installed.

-or-

 The Internet Mail Service is not installed, and the Exchange Server Directory service is not running.

-or-

 The Internet Mail Service is not installed, and the server name or the domain name on SBS 4.5 has been changed. When SBS is restarted the Exchange services do not start and SBS 2000 Setup is started.

During the Requirements Checking phase of BackOffice Server 2000 and SBS 2000 Setup, services are queried to determine the state of the installation. If Exchange Server 5.5 is installed, Setup queries the Exchange Server Directory service to determine whether the Internet Mail Service is present. If the Exchange Server Directory service is not started, the Internet Mail Service lookup does not succeed. Because the BackOffice Server 2000 or SBS 2000 upgrade cannot be completed if the Internet Mail Service is installed, you receive the error message that is described in the &quot;Summary&quot; section of this article.



WORKAROUND
To work around this problem:
 * 1) Cancel Setup.
 * 2) Click Start, point to Settings, and then click Control Panel.
 * 3) Double-click Services, and then start Microsoft Exchange Directory service.

NOTE: If your computer is running BackOffice 4.5 on Windows 2000, use the Services Administration snap-in to perform this step.
 * 1) Start Setup again.

Setup can now query the Exchange Server Directory service and correctly determine that the Internet Mail Service is not present.

If the Exchange services do not start manually after the server name or the domain name is changed, you must change the server and or the domain name back to the original name and then restart the server. The Exchange services start automatically.



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