Ok step further, moved the schema role over to the remote site and re-ran preparead

Now trying to uninstall Exchange to try start fresh I receive -

--------------------------------------------------------
Microsoft Exchange Warning
--------------------------------------------------------
The following warning(s) were reported while loading topology information:

get-ExchangeServer
Completed

Warning:
Object ALCHMAIN has been corrupted and it is in an inconsistent state. The following validation errors have occurred:

Warning:
Cannot calculate value of property "AdminDisplayVersion": "SerialNumber property is not present.".


--------------------------------------------------------
OK
--------------------------------------------------------

From what I'm now reading it looks like theres issues with setting up Exchange in remote sites etc any work arounds to tidy this up?

Ok manually entered the version number in via ADSI edit and the uninstall started but stops on the hub transport role reporting:

This operation could not be performed because object 'servername' could not be found on domain controller 'fqdn etc'

Please any help greatly appreciated as I may be making things worse :)
