How can you remove them and regain the use of that disk space? Cause When you run a Windows update or install a Windows XP Service Pack, many system files are replaced by newer versions. To make it possible to uninstall or roll back an update (in case it is found to be the cause of problems) Windows must preserve copies of all the files replaced in the update. These files are stored in the blue $NtUninstall... folders in the Windows folder. Links to these $NtUninstall folders are placed in the Registry entries for each update, so that Windows knows where to find the uninstall files for each update. Simply deleting the folders would cause these Registry entries to become invalid. In the majority of cases, Windows updates are never uninstalled. If an update does need to be r

KCC The KCC is a built-in process that runs on all domain controllers and generates replication topology for the Active Directory forest. The KCC creates separate replication topologies depending on whether replication is occurring within a site (intrasite) or between sites (intersite). The KCC also dynamically adjusts the topology to accommodate new domain controllers, domain controllers moved to and from sites, changing costs and schedules, and domain controllers that are temporarily unavailable. How do you view replication properties for AD? By using Active Directory Replication Monitor. Start–> Run–> Replmon What are sites What are they used for? One or more well-connected (highly reliable and fast) TCP/IP subnets. A site allows administrators to configure  Active Directory  access and replication topology to take advantage of the physical network. Name some OU design considerations? OU design requires balancing requirements for delegating administrative rights – inde
