FSMO FAQ

Withdrawal From Artificial Sweeteners
In recent years I was asked repeatedly about the FSMO roles. Here I try to make a list of the most repeated questions.
What are FSMO?
are special roles that meets some DC in the domain or forest. Although the AD replication model is multi-master and changes can be made at any DC, some specific changes or controls. The simplest example is that there can be two different passwords DC with the same user, because an attacker could use an old password to gain access to a resource.
FSMO How many are there?
are five different roles. The Domain Master and Schema Master is unique in the Forest, so no matter how many domains we have, there is always one of each. The PDC Emulator, Infrastructure Master and RID is unique in the domain, so if we have two domains have two of each of these three. How many DC
need to perform these roles?
Everyone can coexist in the same DC, but according to the size of the deployment of AD, we can put them in different DC.
not know existed, how do I install them now that I have my AD in production?
When you install the first DC of 5 roles are installed automatically on the DC. Similarly, when you install the first DC of a new domain, the 3 own domain roles are installed on the DC.
What if I put out my first DC, I lost the roles?
Not necessarily, if the decommissioning of the equipment is made correctly, when you run Dcpromo.exe to take the role of DCs in a team, the roles are transferred to another DC that can fill that role.
How I can pass the role to another team?
roles PDC Emulator, Infrastructure Master and RID, since the tool "Active Directory User and Computers", the Domain Master from "Active Directory Domain to Trusts and the Schema Master from" Active Directory Schema "
Where is the" Active Directory Schema "?
The AD Schema is something normally should not be changed, so before you can view the tool Direcroty Active Schema "must register a dll running from a CMD:
" regsvr32 schmmgmt.dll "If I turned evil
my DC, I broke I stole it ... I lost the roles? DC
If you had any role, it is likely that this function is not fulfilling any equipment. It may take some time until the lack of that affect the operative function of the company.
DC If I turned off my bad, I broke, I stole it ... How do I move one role to another team?
In this case we must force the pace of the role using the "ntdsutil", as indicated by the link:

Can any DC can have any role?
No, the RODC can not have any of these roles. Nor can run the Infrastructure Master role is a Global Catalog DC, except that all DCs are Global Catalog.
What if I have one DC?, Then my DC is Global Catalog, right?
Yes, but then all your DC are Global Catalog.
What role does and what happens if you run the Domain Master role? The Domain Master
stores information domains within the forest, if not running, you can not add new domains the forest.
What role does and what happens if you run the Schema Master role?
The Schema Master saves the AD schema information, if not running, you can modify the AD schema.
What role does and what happens if you run the PDC Emulator role?
The PDC Emulator is used for teams with NT 4.0 (I hope nobody's continued use) can authenticate to the network as if it were a NT 4.0 PDC is the DC responsible for keeping passwords of users and computers in AD. If not running, a team with NT 4.0 will not be able to authenticate users or computers and are not going to change your password. What
function does and what happens if you run the role of RID?
The RID numbers distributed within the domain SID. If the RID is not running and a DC wants to create a new object in AD but not to assign SID number, you can not create the object in the DC. (Note: SID is the security identifier, a unique number that each object AD)
What role does and what happens if you run the role of Master Insfrastructure?
The Infrastructure Master is responsible for maintaining the reference group membership of users in different domains. If the role is not available, users can not be moved between different domains.
How I can see where they are running the roles?
Using the same graphical tools that are used to move or run from the CMD: netdom query fsmo

How To Convert A Plug In Lamp
Today Tuesday July 13, 2010 is ending support for Windows 2000 in all versions from Microsoft. There are no more security fixes, functionality patches, updates, articles in the Microsoft website support or assistance. While I think few people still have Windows 2000 as a PC operating system to this date, there are probably several servers installed in service.
What will more people worry about is that there is no plus support for Windows XP SP2 or earlier versions.
I hope everyone has updated their computers!
