The best thing you can do is ensure the Global Catalog is on both of your DCS.<br />
<br />
Also we split our FSMO roles between our 2 DCs... afterall having them all on one is one point of failure...

I advise reading up on the purpose of the FSMO roles and how they work.<br />
<br />
As has been stated, in all but the very largest of environments, your domain should be fine for days, probably weeks, and possibly even months with the FSMO masters offline. &nbsp;<br />
<br />
Splitting them in a single domain environment is basically pointless because of how they work.

Hi,<br />
<br />
I have 2 &nbsp;Windows 2012 DC's. <br />
<br />
DC1 is at my primary site <br />
DC2 is at my DR site<br />
<br />
I want to make sure that if my primary site is down and I need to rely on my DC2 at the DR site the FSMO roles are sync'ed or transferred over. Is this an automatic feature or manual? I need to make sure everything will work if my DC1 at my primary site if down. <br />
<br />
How can I find this out? <br />
<br />
Thanks

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
