Active Directory (AD) is a directory service developed by Microsoft for Windows domain networks. It is used to manage user accounts, computers, and other resources in a Windows network. AD is a critical part of many businesses’ IT infrastructure, and it is important to ensure that it is healthy and functioning properly.
There are a number of ways to check the health of an AD. One way is to use the AD Health tool. This tool can be used to check the overall health of AD, as well as the health of individual AD components, such as domain controllers and replication links.
