SYMPTOMS
When you run Microsoft Exchange Server setup and click Remove All, the following key may still exist in the registry:

HKLM\Software\Microsoft\Exchange\Setup

In Exchange 2000, if a previous installation was not successful, and when the Administrator re-attempted Exchange 2000 Setup, and opted to "remove all," remnants of the original installation still remain under the Exchange Setup key. The Exchange Server Setup Progress.log may display:

[13:10:53]

Prerequisites for Microsoft Exchange Instant Messaging Service failed: The component "Microsoft Exchange Messaging and collaboration Services" cannot be assigned the action "Install" because:

- A server object for this server ("ServerName") already exists in the Administrative Group "AdminGroupName". You must either remove this server object before installing, or run setup with the "DisasterRecovery" switch if you are attempting to recover this server.



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

Microsoft is researching this problem and will post more information in this article when the information becomes available.



MORE INFORMATION
In order to successfully reinstall Exchange 2000, it is necessary to manually delete all subkeys below (but not including) the Setup key.
