In its infancy, AD had some rather glaring flaws. One DC that could make changes to the domain, while the rest simply fulfilled authentication requests.

To resolve that fundamental flaw, Microsoft separated the responsibilities of a DC into multiple roles. Schema is essentially all the attributes associated with an object passwords, roles, designations, etc. The domain controllers, therefore, need to be online at the time the services are needed.

Thankfully, depending on the FSMO role, this may not be all that often. For schema master, for example, the DC only needs to be online during the update. The PDC, however, will need to be online and accessible at all time. For that reason, you need to make the necessary steps to ensure that the PDC emulator does not fall over.
