SYMPTOMS
When you try to remove Exchange 2000 Server from a cluster node, you may not be able to do so and you may experience one or more of the following symptoms:  If you are logged on as an administrator, you may receive an error message that is similar to the following:

The component &quot;Microsoft Exchange Messaging and Collaboration Services&quot; cannot be assigned the action &quot;Remove&quot; because:

You must be at least a Exchange Full Administrator at the Administrative Group level to run setup. You must use an account that has been granted the Exchange Full Administrator role on the current Administrative Group, or a higher level role, by using the Exchange Administrative Delegation Wizard.

 If you are logged on as a member of the Domain Admins security group, the removal continues but is not successful. The Microsoft Exchange Messaging and Collaboration Services component is not removed.



CAUSE
This problem may exist in the following scenario:
 * 1) You install Exchange Server on a cluster node in an organization that contains a non-clustered Exchange 2000 server.
 * 2) You remove the mailboxes from the clustered Exchange Server, and then remove the Exchange Virtual Server, also known as a cluster group, from the cluster node.
 * 3) You remove Exchange 2000 Server from the non-clustered server and remove the organization.
 * 4) You try to remove Exchange 2000 Server from the cluster node.

When you remove the last Exchange 2000 Server, Setup removes the organization from the Microsoft Windows 2000 Active Directory and from the Exchange Administrator. Because of this, you can no longer remove Exchange 2000 Server from the cluster node.



WORKAROUND
To work around this problem, follow these steps:
 * 1) Run the Setup.exe from the Exchange 2000 Server CD-ROM with the /forestprep switch, and then again with the /domainprep switch.
 * 2) Install Exchange 2000 Server on the non-clustered server.
 * 3) Remove Exchange 2000 Server from the cluster node.
 * 4) Remove Exchange 2000 Server from the non-clustered server.



STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server.
