Exchange Accidentally Deleted from AD

Scenario:  We have a SBS 2003 server running Exchange 2003.  In the process of adding an Exchange 2010 Server on Server 2012 we had issues with getting everything to work after Exchange 2010 was installed.  The tech working on the project could not uninstall Exchange 2010 using add/remove programs so they looked into manually removing the new Exchange server from the system so they could build Exchange 2010 on Server 2008R2 (presuming that 2012 and Exchange 2010 would not get along well - we cannot get exchange SP3 installed)

Unfortunately when looking up articles on how to remove the new server, they used a process to remove Exchange from AD - as in all Exchange...  

The following was run in ADSIEdit:

Go to Primary Domain Controller
2. Open ADSIEDIT
3. Right Click on ADSIEdit and Click Connect to
4. Connect to “Default Naming Context”
5. Navigate to the following objects and Delete them.
DC=Domain,DC=Com -> OU=Microsoft Exchange Security Groups
DC=Domain,DC=Com -> CN=Microsoft Exchange System Objects
6. Right Click on ADSIEdit and Click Connect to
7. Connect to “Configuration”
8. Navigate to the following objects and Delete them.
CN=Configuration,DC=Domain,DC=Com -> CN=Services -> CN=Microsoft Exchange
CN=Configuration,DC=Domain,DC=Com -> CN=Services -> CN=Microsoft Exchange Autodiscover
9. Force the Active directory Replication.
10. Exchange 2010 Manual Uninstallation is Completed

The old exchange server is partially functional at the moment but we can no longer get in the management console or use OWA and presume that more problems will follow.  Using ADrestore we have been able to restore all of the AD objects but still cannot access OWA or management console.  No reboot has been performed for fear of a worse issue.

How should we proceed to restore the AD information for Exchange so that the Management console and OWA will function again and we can get back to our upgrade?

Thanks!

Seconded.  I had an issue involving ADSI edit.  I would advise calling Microsoft as well.
