Question : Failed Exchange 2010: Remove data from domain.

I have a failed Exchange 2010 server that I am working to completely redo. The problem is, I want to start 100% fresh, and I am unable to find out how to remove the Exchange data from my DC's without having the old exchange install available. (This is the part where I am pretty sure I am missing something very simple...)
Regardless, the main DC is on Windows 2008R2 Ent. The rebuilt exchange box is the same OS.
I have read several examples of how to remove/uninstall the data while Exchange is still there, but I really want to be sure before I start tinkering with my DC's as they are production and I really don't want to screw them up.
Any push in the right direction would be great.

Answer : Failed Exchange 2010: Remove data from domain.

I have just completed a hosting solution with addresslist seggregation in exchange 2010.
And it was a B**CH.
Not even dave goldman who is an renoved author of ehitepapers on exchange, has managed to do this, to a level he is willing to write about, so I am pretty proud of it.
This however required doing extensive editing with ADSIedit.msc
And a ton of guesswork, since there really arent any good resourcess on exchange 2010 error situations.

The only ressource I have with a list of AD data is this :

Since the install is FUBAR, you couldent really mess things up any worse by deleting these containers from the Exchange service container in active directory.

But as always, try and do thins outside work hours, and have a backup handy.
Also allow time for replication after deleting, before trying to see if the installation will continue.
