How to determine which DC has the Schema Master role. The Microsoft Active Directory schema contains formal definitions of every object class that can be created in an Active Directory forest.

The effects can be anything from the inability to reset passwords to users not being able to logon to a breakdown of AD services.
One of the strangest things about operations master role failures is that many times their effects can be misread as other problems. For example, in a Windows NT environment, if a client has trouble performing some operation with a server, the problem had to be with either the client or with the server, assuming that the user had successfully authenticated into the network in the first place.
