Question : Uninstalling exchange 2007

Hi,
I am trying to uninstall exchange 2007 and all roles are removed and except hub transport role, when I am trying to remove I am getting the following error message
Error :
Property IsProvisionedServer cannot be set on this object because it requires the object to have version 0.1(8.0.535.0) Current version of the object is 0.0(6.56500.0)

Please advise how can I remove completely exchange so that I can reinstalling again
regards
Jinesh

Answer : Uninstalling exchange 2007

if you plan to completely format this box and then install exchange by doing everything again and if there is no other exchange server in this exchange ORG then you can use adsiedit.msc to remove it.
