repadmin

A read-only Active Directory health check with a point-and-click interface. It wraps `dcdiag.exe`, `repadmin.exe`, `nltest.exe`, and `w32tm.exe`, plus a set of native directory checks, behind one window so you can pick exactly which tests to run and against which domain controllers.

PowerShell script for diagnosing, auditing, and monitoring Active Directory replication health across domain controllers.
