IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs.

256986 Description of the Microsoft Windows Registry



SYMPTOMS
In the Component Selection window, when you click Install to install a component of Exchange 2000 Server, you may receive the following error message:

The component &quot;Microsoft Exchange Instant Messaging Service&quot; cannot be assigned the action, Install, because a server object for this server already exists in the Administrative group, AdminGroupName. You must either remove this server object before installing, or run Setup with the &quot;DisasterRecovery&quot; switch if you are attempting to recover this server.



CAUSE
This behavior can occur because the previous installation for this component had not been successful. The computer has retained some information that is related to this component, and the presence of this information prevents the component from being installed.



WORKAROUND
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.

To work around this behavior, modify the registry values under the following registry to &quot;pretend&quot; that the component has been installed successfully, and then remove this component and install it again:

HKEY_LOCAL_MACHINE\Software\Microsoft\Exchange\Setup

For the example that is described in the Symptoms section of this article:  Add the following registry values under the registry:

HKEY_LOCAL_MACHINE\Software\Microsoft\Exchange\Setup

Name: InstantMessaging

Type: REG_SZ

Data:

Name: InstantMessaging Version

Type: REG_DWORD

Data: 0x3c Run Exchange 2000 Setup to remove the Exchange 2000 Instant Messaging component. Run Exchange 2000 Setup to install the Exchange 2000 Instant Messaging component.
