Survival without FSMO
Posted on 2013-10-24
We have recently implemented a windows 2012 environment. This consists of two data centres in different regions. Site A holds the FSMO roles and Site B acts as secondary domain controller. When connectivity is broken with Site A all services in Site B go down and we see repeated 4015 errors. The solution is to restore DNS services from the FSMO.
Our questions are the following:
1) Is it possible for a secondary domain controller (No FSMO) to maintain a site (DNS, AD, etc)?
2) Typically how long will the secondary DC hold up services (DNS, AD, etc) before you have to seize FSMO?
