Exchange KB2810617: Can’t install Exchange Server 2010 SP3 when you define a Windows PowerShell script execution policy in Group Policy

Knowledge-BaseВсем привет!

Сразу же с выходом Exchange 2010 SP3 вышел первый KB2810617, описывающий ошибку при его установке.

Can’t install Exchange Server 2010 SP3 when you define a Windows PowerShell script execution policy in Group Policy.

 

Symptom:

Consider the following scenario:

  • You define a Windows PowerShell script execution policy by applying a Group Policy Object, or you apply a local Group Policy.
  • You try to upgrade an earlier version of Exchange Server 2010 to Exchange 2010 Service Pack 3 (SP3).
  • The setup process fails after the Remove Exchange Files step is completed.

In this scenario, Exchange 2010 does not work on the affected server. Additionally, you cannot restart the setup process.

 

 

Cause:

This issue occurs because the required Windows Management Instrumentation (WMI) service stops during the installation process. The WMI service is needed to query Active Directory Domain Services (AD DS) to verify the Windows PowerShell script execution policy that must run as a part of the setup.

 

 

Resolution:

To avoid this issue, follow these steps:

  • Disable the execution Group Policy by using the Group Policy Management Console (Gpmc.msc) or Local Group Policy Editor (Gpedit.msc). Group Policy objects for the execution Group Policy must be set to Undefined.
  • Install Microsoft Exchange Server 2010 SP3.
  • Re-enable the previously defined Windows PowerShell script execution policy in the Group Policy Management Console or Local Group Policy Editor.

 

Дополнительная информация:

To verify the execution policies before you begin the installation process, run the following Windows PowerShell cmdlet:

Get-ExecutionPolicy -list


The output should resemble the following:

Scope 		ExecutionPolicy 
----- 		--------------- 
MachinePolicy 	Undefined
UserPolicy 	Undefined 
Process 	Undefined 
CurrentUser 	Undefined 
LocalMachine 	Undefined

If any of the execution policies are set to a status other than Undefined, refer to the steps in the «Resolution» section before you install Exchange Server 2010 SP3.
