repadmin

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

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.
