I am trying to remove a CMS and an active cluster and I get the following error during the uninstall: "This specified ScanType (PrecheckUninstall) is not defined in the configuration file." Does anyone know the work around for this?

Hi Bruce, Please let me know your Exchange 2007 build version. In addition, whether have you updated your EXBPA tool? Please also help me gather the exchange setup log for more information. Mike

Hello Mike, My Exchange 2007 version is Version 8.1 (Build 240.6). As far as I know the EXBPA has not been changed or updated. Below is the setup log information.
