Active Directory Health Check

When should I check my active directory health?

Active Directory health depends on technical, organizational, and process factors. While it is easy enough to analyze the configuration of Active Directory and conclude that it is healthy, lack of consistent approach to things, like change control, can introduce randomness to an otherwise stable environment. Ensuring Active Directory is in healthy working order can save costs and proactively identify and reduce risk.
