Part 3: Windows Server 2003 Upgrades (Yahoo free web hosting) and Migrations
Part 3: Windows Server 2003 Upgrades and Migrations Microsoft Windows Server 2003 Inside Out Chapter 7 Following are the results of storing DNS data in various locations: . DNS zone files leave replication to DNS and require administrative configuration. . Windows 2000 Active Directory integrated zones cause DNS data to be replicated to all domain controllers in the domain. . The forest application partition (ForestDnsZones) causes the DNS data to be replicated to all DNS servers in the forest. . The domain application partition (DomainDnsZones) causes the DNS data to be replicated to all DNS servers in the domain. Identify Server Roles You must identify the network services and server roles that an upgraded server or domain controller will need to perform. Network services commonly employed include DNS, Dynamic Host Configuration Protocol (DHCP), Windows Internet Naming Service (WINS), Routing and Remote Access Service (RRAS), Terminal Services, and Internet Authentication Service (IAS). Depending upon expected load, servers can host one or more network services. Carefully assess servers that are domain controllers review your ability to upgrade the server hardware and which secondary roles (such as global catalog server) the server will perform. Consider server performance and operational requirements for domain controllers on your network. Although large networks commonly have dedicated DNS servers, on small networks a server might provide multiple network services (such as DNS and DHCP) in addition to domain controller roles such as Active Directory access, Kerberos, and global catalog operations. Evaluate which operations master roles the domain controller will support; forest-wide roles (Schema Master and Domain Naming Master) and/or domain-wide roles (RID Master, Infrastructure Master, and PDC Emulator). Tip The PDC Emulator supplies the Windows Time Services to synchronize all other domain controllers in the domain servers that are assigned this role should receive particularly close scrutiny to ensure system reliability. For upgrades from Windows 2000, you can continue to use the assigned operations master roles, yet operations master roles must be determined for each domain controller when upgrading a Windows NT 4 domain controller. For more information on operations master roles, see the section entitled Establishing Operations Masters on page 248. 224
