You can promote the Backup Domain Controller to be the Domain Controller, this must be done manually though.

As long as your authentication is not coming from the DC, nothing really happens to SAP app servers.

If it is a portal that uses a DC for Active Directory for it's LDAP and that DC goes down, no one but the users that are in the local portal data base will be able to log in. From that point, log into the configtool.bat and change the LDAP server to the secondary controler until the primary is restored.

the question is not related to SAP product.

Check MS support site for more information on DC.
