Problems and Symptoms

Let's take a look at the symptoms and then the causes.

Symptoms

The database gets corrupted and the DC is no longer able to process and authenticate or perform directory lookups. This becomes apparent when replication fails for some reason, or a large amount of specific event log errors appear. Another symptom could be that the AD services don't start on the DC.
