How to perform active directory health check: As an administrator you have to check your active directory health daily to reduce the active directory related issues, if you are not monitoring the health of your active directory what will happen

Let’s say one of the Domain Controller failed to replicate, first day you will not have any issue. If this will continue then you will have login issue and you will not find the object change and new object, that’s created and changed in other Domain Controller this will lead to other issues

If the Domain Controller is not replicated more then 60 day’s then it will lead to Lingering issue
