Pesan kesalahan yang salah satunya dapat berpeluang terjadi di saat kita melakukan migrasi dari Windows Server 2008 ke Windows Server 2008 R2 adalah di sisi Group Policy Object-nya.
An error has occurred while collecting data for Software Restriction Policies.
This error impacts the following settings:
Software Restriction Policies
Software Restriction Policies/Security Levels
Software Restriction Policies/Additional Rules
The following errors apply to all of the above settings:
An unknown error occurred while data was gathered for this extension. Details: Unable to cast object of type 'System.String[]' to type 'Microsoft.GroupPolicy.Reporting.Extensions.Registry.UnknownType'.
Solusinya kita dapatkan di http://support.microsoft.com/kb/981750 segera unduh hotfix yang sesuai dengan operating system yang digunakan, dan GPO tersebut kembali berjalan normal.
Semoga bermanfaat.
