Domain not available

[Guus Ellenkamp]

I have two domain controllers. If one of them is switched off, the other
does not seem to take over. What could be wrong?

In Windows 2000 and 2003, PDC and BDC doesn't exist anymore but there is 5
roles (FSMO Roles) that are managed by a DC. By default, the first DC of the
forest and domain manage all roles.

2 roles are for the forest
3 roles for the domain

Here you can find more informations about it.

To have windows domain redundancy, you should have 2 DCs with the global catalog role. Also make sure you have two DNS server for the redundancy. This post may help too,
