A. To monitor or change replication, you must use the Microsoft Management Console (MMC) Active Directory Sites and Services snap-in. This tool lets you view, create, or delete connection objects. Other tools you can use include the Microsoft Windows 2000 Resource Kit’s Repadmin and Replmon tools.

Repadmin is a command-line tool that lets you check replication consistency (e.g., for a Knowledge Consistency Checker—KCC—recalculation). The switch /showreps displays a list of replication partners, as well as reasons for problems. The invocation ID is the database globally unique ID (GUID).

When you use Repadmin with the switch /showreps, you’ll see text such as the following.
