Exchange 2003 Installation Problem

Environment:

Exchange 2003 Cluster and 2 Exchange 5.5 Servers.

We recently had some consultants install the 2003 cluster to take place of one of the Exchange 5.5 servers.  Now, I was trying to install Exchange 2003 on a new server to take place of our other Exchange 5.5 server and ran into some issues during installation.  The installation said unsuccessfull.  The exact error was "moduleid not found in map in getsetupcomponentbymoduleid"  I found an article about this error, although not the same version of Exchange,  and it said to make 3 entries in the registry ( http://support.microsoft.com/default.aspx?scid=kb;en-us;839495 ).  I tried that and retried the installation but received another error"

"The component "Microsoft Exchange Messaging and Collaboration Services" cannot be assigned the action "install" because: - A server object for this server ("server-name") already exists in the Administrative Group "####".  If you are attempting to recover this server please run setup with the "DisasterRecovery" switch otherwise you must first remove this server object from the Active Directory by using the Exchange System Manager."

(I also receive this error when trying to uninstall MS Exchange from Add/Remove programs)

Well, there is no Exchange System Manager yet on this particular server b/c the installation didn't get that far.  So, I went into our existing Exchange 2003 and it was in there.  So I tried to remove it and got the following error:

"The server "server-name" cannot be removed because:  -  You must be at least a Full Exchange Administrator at the Administrative Group level to run setup.  You must use an account that has been granted the Full Exchange Administrator role on the current Administrative Group containing the current Routing Group, or a higher-level role, using the Exchange Administrative Delegation Wizard.

Facility: Exchange System Manager
ID no: c103f492
Exchange System Manager"

Now, I have tried logged in as both Administrator and Exadmin.  I used to Exchange Administrative Delegation Wizard to give both accounts Full Exchange Administrative rights.  I am so lost and appreciate anyone's help.

Thank you in advance!

It sounds to me like you did not go throught the exchange instalation checklist before you started the install of exchange.

Check the following document for step-by-steps for installing exchange 2003:

This is the document I used when I did my migration from 2000. The  steps should be the same in your enviroment.  

Here is a checklist for 5.5 migrations:
