Sieze FSMO Roles From Failed Server

Hi All,
I have a DC that failed on me.  It was my operations master server.  I setup a new DC that I want to take over that role....  

How can I transfer this?

Did you have another DC in the domain prior to the failure - if so then you can transfer the roles as detailed at Transfer all the FSMO roles to the new DC: See http://www.petri.co.il/transferring_fsmo_roles.htm

You also need to make it a Global Catalog and DNS server

Intstall DNS. You can do this through Add/Remove Programs->Windows Components->Networking Services->DNS.  If you are using Active Directory Integrated DNS then DNS will br replicated from the other DC/DNS.

Next make the new machine a global catalog server, go to Administrative Tools, Active Directory Sites and Services, Expand, Sites, Default first site and Servers. Right click on the new server and select properties and tick the Global Catalog checkbox. (Global catalog is essential for logon as it needs to be queried to establish Universal Group Membership)

If you did dot have a second DC prior to the failure and you cannot recover the old one and have no back up then you will need to rebuild the domain again from scratch

If the DC has failed, you will need to seize the OM role's as you no longer have the original role holder to transfer from.  Anyway this process should be done with caution though it is fairly straight forward.  Here is a link to the Microsoft KB on the subject: support.microsoft.com/kb/255504. Also you will want to read this article which is very informative : http://www.petri.co.il/seizing_fsmo_roles.htm

Hope this helps,
Marc
