Seizing an FSMO can be a destructive process and should only be attempted if the existing server with the FSMO is no longer available.
Seizing an FSMO can be a destructive process and should only be attempted if the existing server with the FSMO is no longer available.If the domain controller that is the Schema Master FSMO role holder is temporarily unavailable, DO NOT seize the Schema Master role.If you are going to seize the Schema Master, you must permanently disconnect the current Schema Master from the network.If you seize the Schema Master role, the boot drive on the original Schema Master must be completely reformatted and the operating system must be cleanly installed, if you intend to return this computer to the network.NOTE: The Boot Partition contains the system files (\System32). The System Partition is the partition that contains the startup files, NTDetect.com, NTLDR, Boot.ini, and possibly Ntbootdd.sys.The Active Directory Installation Wizard (Dcpromo.exe) assigns all 5 FSMO roles to the first domain controller in the forest root domain. The first domain controller in each new child or tree domain is assigned the three domain-wide roles. Domain controllers continue to own FSMO roles until they are reassigned by using one of the following methods:
try this command netdom query fsmo (it will show FSMO roles in current Domain) netdom query fsmo /d:Domain FQDN (It will show FSMO roles in other domain mentioned after /d:
There is no releation between FSMO roles and replication. However Infrastructure master role replicate the cross domain group membership changes.
The ntdsutil command utility will allow you to transfer and seize a FSMO role.
FSMO stands for the Flexible single Master Operation, there are 5 types of FSMO Schema Master Domain Naming Master Infrastructure Master Remote ID Master(RID) PDC Emulator Regards Anil Mahapatra
the server which holds the FSMO role it cna be changed by few methods 1. go to admin option->users and computers -> select domain->rt click fsmo roles gives three tabs of domain fsmo role holder-> change from there. 2 for other roles go to admin option->use site -> forest level roles you can cchange in the properties of each fsmo role holder. 3. NTDS util will help you to see the roles and transfer
The server which holds the PDC FSMO role it can be viewed by few methods 1. go to admin option->users and computers -> select domain->rt click fsmo roles gives three tabs of domain fsmo role holder. 2 for other roles go to admin option->use site -> forest level roles you can see in the properties of each fsmo role holder. 3. NTDS util will help you to see the roles.
Difference between DC & ADCThere is no difference between in DC and ADC both contains write copy of AD. Both can also handles FSMO roles (If transfers from DC to ADC). Functionality wise there is no difference. ADC just require for load balancing & redundancy. If two physical sites are segregated with WAN link come under same domain, better to keep one ADC in other site, and act as a main domain controller for that site. This will reduce the WAN traffic and also user authentication performance will increase.
First Domain controller in the forest
Windows 2000/2003 Active Directory domains utilize a Single Operation Master method called FSMO (Flexible Single Master Operation), as described in Understanding FSMO Roles in Active Directory. In most cases an administrator can keep the FSMO role holders (all 5 of them) in the same spot (or actually, on the same DC) as has been configured by the Active Directory installation process. However, there are scenarios where an administrator would want to move one or more of the FSMO roles from the default holder DC to a different DC. Windows Server 2003 Active Directory is a bit different than the Windows 2000 version when dealing with FSMO placement. In this article I will only deal with Windows Server 2003 Active Directory, but you should bear in mind that most considerations are also true when planning Windows 2000 AD FSMO roles
Active Directory in general uses a multimaster scheme for updating the directory databases between domain controllers, there are specific functions that can only be performed on specific domain controllers. These specific functions are assigned to one of the five FSMO roles, (pronounced "fiz-moe roles") which can be assigned to one or more Domain Controllers.
