Error message when you try to change a user right which includes a virtual account that has the "NT Service\" prefix in Windows Server 2008 or in Windows Vista: "An external error has occurred"

Applies to: Windows Server 2008Windows VistaWindows Server 2008 Service Pack 2

Symptoms


Consider the following scenario:
  • You have a computer that is running Windows Server 2008 or Windows Vista.
  • You add a user account to a user right on the computer by using the local security policy. For example, you add a user account to the Logon as a service user right.
  • The user account has the NT Service\ prefix.
  • You try to change the user right again by using the local security policy.
In this scenario, you cannot change the user right, and you receive the following error message:
An external error has occurred. Failed to save Local Policy Database
Additionally, the user account that you added is removed from the user right. 

For example, consider the following scenario:
  • You install Microsoft SQL Server on a computer that is running Windows Server 2008.
  • You add the following user accounts to the Logon as a Service user right by using the local security policy:
    • NT Service\MSSQLSERVICE
    • NT Service\MSSQLFDLauncher
  • You try to change the Logon as a service user right by using the local security policy.
In this scenario, you receive the error message that is mentioned earlier.

Additionally, the two user accounts are removed from the user right. Therefore, SQL server cannot start.

Cause


This issue occurs because the Group Policy Management Editor does not support user accounts that have the NT Service\ prefix.
