How to remove Exchange 2010 server

We've just installed Exchange 2010 Standard on a new server and it currently co-exists with our current Exchange 2003 server.
There is only one user mailbox on the Ex2010 server so far, and we've since run into major hardware issues on the 2010 box that leads me to suspect a compromise of the OS and Exchange 2010 installation. This server is holding hub transport, cas, and mailbox roles.
Also, I am running another installation of Exchange 2010 in a VM on a different box (temporarily) with the CAS role only for OWA to work for  mailboxes that were moved to the Exchange 2010 server.....this would go away once all mailboxes were moved.
Now that the hardware problems have been resolved, I'd really like to flatten the box and start over.
What is the process for safely uninstalling Exchange 2010 from the current org and ensuring it doesn't affect the current Exchange 2003 environment ?
A little more info.....my AD is domain and functional level of Windows 2003, and I do have a 2008 DC running. Obviously, AD and Schema were prepped to accept the EX2010 installation.
Thank you.....

Correct....no impact if your not using it to recieve as your internet inbound or outbound email server.    Or OWA or Outlook Anywhere which my guess is you are not.

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

You could scrap the box and setup the Exchange server on a new box or a clean reinstalled OS on the same box.

Here are the steps for recovering an Exchange 2010 server:

(Most Exchange Configuration lies in Active Directory, so Exchange setups uses what it finds in AD in order to assign server roles, configurations and so on)

I didn't intend to mislead.....the server is up and running and functional at this time. I just don't have a level of confidence going forward as far as the OS and Exchange installs currently on there and would much rather start from scratch now that the hardware problems have been resolved.....
Would an uninstall of Exchange 2010 on the box be going down the wrong road ? Would the uninstall impact my current 2003 Exchange server operations ?
I will read the link......looking forward to further comments\suggestions.

Thanks !

Oh oh...ok yes the best solution to remove your Exchange 2010 server would be to uninstall.

OK....just to confirm.....an uninstall of the Exchange 2010 server should have no impact on my current Exchange 2003 server currently running ?
For example, one of my concerns ( based on fact or fantasy I'm not sure of at this point) is that during the uninstall it probably (?) makes modifications to AD based on the removal of this 2010 mail server and could there be a possibility of these modifications having an affect on Exchange 2003 and its objects and attributes in AD ?

thanks in advance for your patience....:>)
