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
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
The use of the Server 2k3 after migration of Migration of Active Directory 2003 to 2008 is to transfer fsmo roles and to demote windows.
There are five roles:They are further classified in two1. Forest RolesSchema Master - As name suggests, the changes that are made while creation of any object in AD or changes in attributes will be made by single domain controller and then it will be replicated to another domain controllers that are present in your environment. There is no corruption of AD schema if all the domain controllers try to make changes. This is one of the very important roles in FSMO roles infrastructure.Domain Naming Master - This role is not used very often, only when you add/remove any domain controllers. This role ensures that there is a unique name of domain controllers in environment.2. Domain RolesInfrastructure Master - This role checks domain for changes to any objects. If any changes are found then it will replicate to another domain controller.RID Master - This role is responsible for making sure each security principle has a different identifier.PDC emulator - This role is responsible for Account policies such as client password changes and time synchronization in the domain

Flexible Single Master Operations servers. They are servers that every Active Directory needs that serve a single purpose. Here are the FSMO servers: Schema Master Domain Naming Master Infrastructure Master Relative ID Master PDC Emulator Those are the five FSMO server rolls that get assigned to 1 or more domain controllers in each domain. Schema and Domain Naming Master will have only 1 server per AD Forest.
AD
The model tells you how much you need to multiply an initial autonomous change in AD (aggregate demand) to determine the total change in AD.

According to Ad Ages downloadable pdf rates chart, the largest ad is a whole page, and the rates change by how long you want the ad for. They start at 100, and end at 500 dollars.
