|To copy a WMI Filter|
In the Group Policy Management Console (GPMC) console tree, click the WMI filter in the forest and domain containing the WMI filter that you want to copy.
Right-click the WMI filter you want to copy, and then click Copy.
In the destination domain, right-click WMI Filters, and then click Paste.
To complete this procedure, you must have privileges to create WMI filters in the domain in which you want to create the filter. By default, the Domain Administrators, Enterprise Administrators, and Group Policy Creator Owners groups have this permission.
WMI Filters is only available if at least one domain controller in the domain is running Microsoft Windows Server 2003. The same is true for WMI Filtering on the Scope tab for Group Policy objects.
