I'm trying to uninstall an exchange 2007 server.  this server was recovered solely for the purpose of gracefully removing exchange from it.  I recovered it using the /m:recoverserver switch.  The only components that remain are the mailbox role and mgmt tools.  When trying to uninstall I get the following message
"Summary: 2 item(s). 0 succeeded, 1 failed. Elapsed time: 00:00:00
Mailbox Role - Failed Error:Setup previously failed while performing the action "DisasterRecovery".  You cannot resume setup by performing the action "Uninstall".

The ExchangeSetup Log shows the following messages.  How can I properly uninstall Exchange?  I'm truly beat down on this one.

    When you run setup, do you have any other options other than uninstall?

    From add/remove programs I can either change or remove.  If I select change and try to add another role, just to try, it fails as well.
