FSMO Roles on two separate servers

Is it possible to run Windows 2003 fsmo roles on two separate Domain Controllers? Such that if one was to fail, the other would be able to satisfy all other requests.

This explains how to split / distribute them:


This explains how to seize them in the event of a failure:

You are supposed to split the roles between DCs but you can not run two complete sets of roles on two servers you can only split them.  Good thought but it's not possible, you can however seize the roles in the event of a failure and then bring them up on another DC.  It doesn't happen automatically but there is a way to do it.

Realistically you won't notice that one of the FSMO role holders is down right away. You could function fine for a few days with them being offline as they are mainly for administrative functions.

There is no need to have redundancy with them because, as stated, they can be seized if needed. But seizing a role should be a last resort.

Here's a good article listing the functions of the FSMO roles.

Hi biggiesmallzz,

The answer is no. All you can do is to assign "stand by" FSMO for particular role which should have direct connection to FSMO server. In case FSMO server fails, you have to seize roles manually .Seize only PDC emulator role and Infrastructure role if there is a chance that original server comes back online. Only if FSMO role holder is not coming back online, seize Schema master, Domain Naming Master and RIS master roles.
