CREATING THE LOGICAL DESIGN FOR A NETWORK SERVICES INFRASTRUCTURE

  1. Administrators have three choices for the name of an Active Directory network: the same name as the public name, a delegated subdomain, and a completely different name. The choice will be based on the inherent advantages and disadvantages of each. It will affect administration, security, and ease of use of the network.

  2. Windows Server 2003 requires TCP/IP and DNS to operate at all. This is partially because it uses SRV (Service) records in DNS to locate domain controllers and Global Catalog servers.

  3. A zone is a discrete, contiguous portion of a DNS namespace. Zone information is contained in a zone database file. Adding the words database file to the word zone sometimes helps tremendously when answering a question relating to zones.

  4. A standard primary zone database file is the original database of a zone. It can be written to and read from as well.

  5. A standard secondary zone database file is a copy of the original database for a zone. It can be read but not written to, except through zone transfer. Standard secondary zones are used for load balancing between DNS servers.

  6. Servers that host a standard primary zone can be master servers for other servers that host the standard secondary database for that zone.

  7. DHCP can interoperate with DNS and thereby register hostnames of clients in the DNS database. Clients that can register their own A (host) records include Windows 2000 Professional and Windows XP Professional.

  8. Active Directory integrated zones are preferred when available. Active Directory integrated zones do not use zone transfer, but instead piggy-back their zone change information on Active Directory replication. Active Directory zones are all primary, but they can be set for only secure updates.

  9. Stub zones are special zones that contain only the SRV record, name server record, and glue A host record (IP address) for the zone. These zones are used in networks with noncontiguous namespaces to make DNS name resolution more efficient.

  10. Windows Internet Name Service (WINS) is still used in Windows Server 2003. It provides NetBIOS name resolution for legacy clients and applications. WINS will be needed until all legacy clients and applications are removed from the network.

  11. Push replication occurs between two WINS servers after a specified number of changes on a database. Pull replication occurs on a specific interval, regardless of the number of changes.

  12. Remote access policies define when, where, and how a user can gain access to a network from a remote location. They contain the elements of conditions, permissions, and profile.

  13. Internet authentication services centralize authentication and logging for multiple RAS servers. In regard to IAS services, the RAS servers are the client of an IAS server.

  14. Servers, network printers, and router interfaces should always have static IP addresses. Clients should have addresses that are assigned by a DHCP server whenever possible.
