Reinstall Exchange - Prompted for Exchange 5.5 org

I have an Exchange 2003 server that, due to an error on my part, the organization got deleted from the Services container in ADS&S.  So I am trying to reinstall Exchange 2003, but when I click on Reinstall, I keep getting a prompt to "Select a server in an Exchange 5.5 Organization"?  I tried to reinstall using the Disasterrecovery switch, but then I get a prompt saying I have to run Forestprep (which I've already run) or that the server object must exist in Active Directory in order to recover this server.

Please help!

Do you have any backups of this server, or your domain controller?

If so, you could have a backup of the active directory, and try to restore that. Check out this article;

Us ADSIEdit to get the name you want to restore, it will have to be typed properly.

Good luck,

Either you have an ADC somewhere or you have selected to install the Active Directory connector. When you install Exchange you should be selecting the typical installation only unless you need the additional components. They are not required for the majority of installations.

* Exchange Organization is removed from Configuration Container which means you need to set up Exchange from scratch!!!

* Either you restore AD backup using Authorative Restore (http://support.microsoft.com/kb/840001/en-us)

ntdsutil "authoritative restore" "restore subtree <container DN path>" q q
For example, to auth restore the Mayberry OU of the Contoso.com domain, use the following command:
ntdsutil "authoritative restore" "restore subtree ou=Mayberry, dc=contoso,dc=com" q q

Note - Repeat this step for each peer OU that hosts deleted users or groups.
Important - When you restore a subordinate object of an OU, all the deleted parent containers of the deleted subordinate objects must be explicitly auth restored.

* Roll back from failed migration & do it again http://support.microsoft.com/kb/839356/en-us
