Exchange 2010 setup /prepareAD fails to run

I've tried installing Exchange 2010 on Windows Server 2008 R2 (only domain controller and all-in-one system).

I did setup.exe /prepareAD, setup /prepareSchema and it worked fine the first time I did it.

Unfortunately due to problem with Hub Transport installation related to (at least from what I've read) IPv6 being disabled (some say disabling it helped them while some enabling helped them). I did it the proper way by using registry entry to disable IPv6 but it still errored out. So i managed to uninstall everything (renamed some old entries in registry of failed Hub Transport roles and tried to reinstal Exchange after rebooting server.

Unfortunetly running setup /prepareAD now gives an error:

D:>setup /PrepareAd

Exchange Server setup encountered an error.

Unfortunetly if i rerun the setup it complains that it needs setup /prepareAD to be run first.

Basically all that works now is setup /PrepareSchema and setup /PrepareDomain complains that prepareAD wasn't done.

For full information I'm also attaching error I had before I've uninstalled everything and tried again:

• I've managed to fix this by manually removing every trace of Exchange on this server (not all steps were found at my server but i post them anyway). And kids don't do this at home. This is not supported and may harm your system. I was desperate:

  1. Run setup /m:uninstall
  2. Stop and disable all the Exchange 2010 services
  3. Use Registry Editor (Start->Run->Regedit) to remove these Exchange related registry keys:
     * HKLM\SOFTWARE\Microsoft\Exchange
     * HKLM\SYSTEM\CurrentControlSet\Services\MSExchange* (all the keys starting with “MSExchange”)
     * HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Microsoft Exchange
  4. Remove the entire Web Server role (don’t forget to reinstall afterwards as it’s a prerequisite for E2K10!)
  5. Remove the Exchange 2010 server from Active Directory. I ended up deleting the entire “Microsoft Exchange” branch from ADSIEdit (Configuration Container > Services > Microsoft Exchange) as my Org only counts one server.
  6. Use Windows Explorer to delete:
     * C:\Program Files\Microsoft\Exchange Server
     * C:\ExchangeSetupLogs
  7. Use Windows Installer CleanUp Utility to remove all the exchange related info from the installer database.
  8. Remove the security groups created by Exchange setup from AD
  9. Use CC Cleaner to remove registry entries for Exchange

  I also found this link which gives a bit bigger overview: http://msexchangehelp.wordpress.com/2010/02/10/manually-uninstall-last-exchange-2010-server-from-organization/

  Anyways it solved the problem that installation went thru but again I am at square one with corrupted installation since Hub Transport failed to install AGAIN. So redoing this steps again... and trying installation again with IPV6 disabled.
