Exchange Removal

Hi, I have just started a contract where the Exchange install has been fudged.

The previous IT provider installed Exchange 2007 and migrated the users across, set up routing group connectors etc this part is fine.  What they did was to just remove (physically) the old Exchange 2003 servers.  Now these are referenced in AD along with the old routing groups.

What is the best was of removing all the 2003 components?

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The process is described in my first response with the Microsoft KB above...

Remove the Exchange Server 2003 server from Active Directory
To remove the Exchange Server 2003 server from Active Directory, follow these steps.

Note This procedure removes all references to the server in Active Directory. It also removes the mailbox-enabling attributes from all Active Directory users who have mailboxes on the server that you removed.
Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.
Expand Administrative Groups/Your_Administrative _Group_Name/Servers.

Note In this step, replace Your_Administrative _Group_Name with the name of your administrative group.
Right-click the name of the Exchange Server 2003 server that you want to remove, click All Tasks, and then click Remove Server.
If you cannot install or run Exchange System Manager, you can use the Active Directory Service Interfaces (ADSI) Edit snap-in to manually remove enough of the server attributes so that you can try a successful reinstallation. This method does not perform cleanups of references to the server object outside the server's own container. We do not recommend that you use this method unless you intend to immediately reinstall the server in the same administrative group. This is because you may have to manually remove or edit many attributes on objects throughout Active Directory.

The ADSI Edit snap-in is available in Windows Support Tools. For more information about how to install Windows 2000 Support Tools, click the following article number to view the article in the Microsoft Knowledge Base:
301423  How to install the Windows 2000 Support Tools to a Windows 2000 Server-based computer
Warning If you use the ADSI Edit snap-in, the LDP utility, or any other LDAP version 3 client, and you incorrectly modify the attributes of Active Directory objects, you can cause serious problems. These problems may require that you reinstall Microsoft Windows 2000 Server, Windows Server 2003, Microsoft Exchange 2000 Server, Microsoft Exchange Server 2003, or both Windows and Exchange. Microsoft cannot guarantee that problems that occur if you incorrectly modify Active Directory object attributes can be solved. Modify these attributes at your own risk.
To use the ADSI Edit snap-in to remove an Exchange Server 2003 server from an Exchange Server 2003 administrative group, follow these steps:
Click Start, point to Programs, point to Windows 2000 Support Tools, point to Tools, and then click ADSI Edit.
Expand the following items:
Configuration Container
CN=Configuration, DC=Domain_Name,DC=com
CN=Microsoft Exchange
CN=Administrative Groups
Note In this procedure, Domain_Name represents the name of your domain, Your_Organization_Name represents the name of your organization, and Your_Administrative_Group_Name_Or_Exchange5.5_Site_Name represents for the name of your administrative group or Exchange Server 5.5 site.
Right-click the Exchange Server 2003 server object, and then click Delete.
Click Yes in every adsiedit dialog box that prompts you to confirm the deletion.
