Error message when you try to install Exchange Server 2010 SP2: “AuthorizationManager check failed”:
Consider the following scenario:
- You install Microsoft Exchange Server 2010 or Microsoft Exchange Server 2010 Service Pack 1 (SP1). (okay SBS 2011 includes Exchange 2010 sp1 – check)
- You use the Group Policy Management Console (GPMC) or the Local Group Policy Editor (Gpedit.msc) to create a Group Policy Object (GPO) or a local policy . (We do have group policies – check)
- The GPO or the local policy sets the Windows PowerShell Execution policy to a status other than Undefined. (SBS 2011 does NOT do this and thus will not be impacted by this)
- You install Microsoft Exchange Server 2010 Service Pack 2 (SP2).
When this error occurs, Exchange Server 2010 does not work and is not listed in Add or Remove Programs. Additionally, you cannot reinstall Exchange Server 2010.
This issue occurs because the Windows Management Instrumentation (WMI) service is stopped during the installation process. Therefore, the ServiceControl.ps1 Windows PowerShell script that runs as part of the Exchange Server 2010 SP2 installation process cannot call the WMI service to verify the execution permissions.
To resolve this issue, follow these steps:
- Recover the server that is running Exchange Server 2010
Ouch. Bottom line, SBS is not impact. But for anyone else out there installing SP2, you might want to check your PowerShell and ensure you have not set a policy.
