  • Seize FSMO roles on the SAME DC?

    Hi,

    I have problems with my DC that holds FSMO roles.
    My configuration:

    1. Windows 2008 Server (64bits) - installed and configured as DC with Active Directory, DNS, DHCP, DFS replication etc.

    2. Windows 2008 Server (64bits) - installed as additional DC, works in separated network (two sites connected with VPN).

    The goal is to use separated DCs on this two networks and share data with DFS file replication. Everithing works well for a week, but now ont the primary DC i've got this error:

    Warning:

    This server is the owner of the following FSMO role, but does not consider it valid. For the partition which contains the FSMO, this server has not replicated successfully with any of its partners since this server has been restarted. Replication errors are preventing validation of this role.

    Operations which require contacting a FSMO operation master will fail until this condition is corrected.

    FSMO Role: CN=Schema,CN=Configuration,DC=xx2,DC=local
    I've got separated errors for all roles.

    Please note that primaty DC has no hardware problems and is up and running. DFS Replication works, but DNS stops to respond and login is very slow on all workstations. Restarting of DNS helps for some time but stops again...

    I'm sure that I have seen this error before in other network and solution was to seize all FSMO roles to the same DC.

    Can seizing roles tho the same (working) DS lead to any problems? How to backup Active Directory just to be sure that I can go back?

    That depends on what backup software you're using, but... http://www.google.co.uk/search?q=win...tive+directory

    Edit: And keep in mind that you should already be taking backups of AD - that is as vital to your business as your Exchange mailstores or the data on your fileservers.

      Thanks for your help about backup. My question was about quick backup of AD only, I do full image backups

      But I want to know about seizing on the same DC, this is the main question...

        A backup of System State is what you need.

        I tend to use NTDSUTIL when seizing roles.
