Consider the following scenario. You have a computer that is running Windows Vista or Windows Server 2008. You use the Group Policy Management snap-in of Microsoft Management Console (MMC) to browse Group Policy objects. However, when you select a Group Policy object, the Group Policy Management MMC snap-in responds slowly or even stops responding. In this scenario, you have to wait awhile before the MMC snap-in responds again.

Note: This problem usually occurs in a domain that has lots of organizational units (OUs). For example, you select a Group Policy object in a domain that has more than 100,000 OUs. In this example, it may take the Group Policy Management MMC snap-in about a half hour to resume responsiveness.
