How do configure a new Windows 2000 DNS server within an existing DNS environment

How do I install and configure a new Windows 2000 DNS server within an existing DNS environment where Active Directory is not enabled?
To create a new Windows 2000 DNS Server, you must install Windows 2000 Server or Advanced Server on a server that is attached to your network. Because DNS is not installed by default during installation of Windows 2000 Server or Advanced Server, you have to install DNS on the server. You can install the Windows 2000 DNS service either during the installation of Windows 2000 Server or Advanced Server, or after the initial installation.

Daniel's DNS Recommendations

If you are looking to really master DNS, Active Directory or other Windows networking skills, I strongly recommend that you try Train Signal. I've discovered this company a few months ago and I always send people their way because the training is so good. You can see more DNS and windows server training with "Hands-On" video instruction at http://www.TrainSignal.com.

If your existing environment already has a DNS domain and an existing DNS infrastructure, and Active Directory is enabled, you can delegate a sub-domain of your existing DNS domain to the Windows 2000 domain. The Windows 2000 DNS server must already be installed to complete the following step.
With an existing DNS domain, you can delegate a sub-domain from the existing DNS server to the Windows 2000 DNS server. For example, if your domain name is mycompany.com, you can create a sub-domain with the name windows2000.mycompany.com. The Windows 2000 DNS server has authority over that sub-domain.
To create the sub-domain, configure the DNS server to use one of the organization's main DNS servers as a forwarder. A forwarder provides recursive lookups for any queries that the DNS server receives that it cannot answer based on its local zones. After you set up the forwarder, the Windows 2000 DNS server is responsible for resolving any queries for computers or resources that are contained within its own local domain. Any queries beyond this range, however, are forwarded directly to the organization's main DNS servers for resolution.
To Add the Organization's Main DNS Servers to the List of Forwarders on the Windows 2000 Server:
1. Click Start, point to Programs, point to Administrative Tools, and then click DNS to start the DNS Management Console.
2. Right click the DNS Server object for your server in the left pane of the console, and click Properties.

3. Click the Forwarders tab.
4. Check the Enable forwarders check-box.
5. In the IP address box enter the IP address of the DNS servers you want to forward queries to - typically the DNS server of your ISP. You can also move them up or down. The one that is highest in the list gets the first try, and if it does not respond within a given time limit - the query will be forwarded to the next server in the list.

6. Click OK.

Networking
Q1: How many type of simple networking?
Ans :

Q2: How many Topologies for networks?
Ans:
STAR, BUS, LINEAR BUS STAR
10BaseT 10Base2 100BaseVG AnyLAN
100BaseX 10Base5
MESH – common WAN topology – remote sites over multiple communications lines. Routers determine best path.

Q3: How many type of OSI models?
Ans: seven type of OSI models-
APPLICATION – software (what you see on screen)
PRESENTATION – translation, compression
SESSION – security and name recognition to allow applications to communicate.
TRANSPORT – insures packets are delivered error free. (flow control, error handling)
NETWORK – addressing messages and translating logical addresses into physical addresses.
DATA LINK – packages bits into data frames (includes control & CRC)
PHYSICAL – electrical, optical, mechanical.

Data Link breaks down into MAC Layer and Logical Link Control Layer
Logical Link Control handles error and flow control
MAC Layer handles access control.
802 Network Model – Defines Network standard for the physical part of the network.
802.3 – CSMA/CD – LAN Ethernet
802.5 – Token Ring - LAN Token Ring

Q4: What is Baseband?
Ans: digital over single frequency.

Q5: What is broadband?
Ans: analog signal over a range of frequencies, nondiscrete unidirectional signal.

Q6: How many type of Protocols?
Ans: Protocols are-
DLC – non-routable - used for HP Printers (Jet Direct) and IBM Mainframe Connectivity.

Q7: What is HCL?
Ans: HCL – Hardware Compatibility List – lists all hardware that is compatible with Windows NT.

Q8: What is PDC and BDC?
Ans: PDC - Primary Domain Controller – Logins, Permissions, Scripts, Securities.
BDC - Backup Domain Controller – a computer that receives a copy of the domain’s security policy and database and authenticates network logons. (It provides a backup in case the PDC becomes unavailable. It is not required but is recommended to be a backup to the PDC.
NT allows you to decide who can and can not print.
NT Service is an application that allows you to add services MAC Service (need service to be able to connect to other OS’s).

Ans: Global – created on PDC containing user accounts only from their own domain account database.
Local – individual user accounts have rights and permissions on local computers.
Universal:-
Special – used for internal system access to resources and permissions.
Built-in – perform common network admin and maintenance tasks.

Q11: What is SNMP?
Ans: SNMP (Simple Network Management Protocol) –
Part of TCP/IP Suite – programs called agents monitor network traffic and behavior.
Store data in MIB’s (management information database)
Records hubs, servers, NIC’s, routers.
Sends an ALERT to Network Manager If beyond certain ranges.

Q12: What is SMS?
Ans: SMS (Systems Management Server) Microsoft’s back office product allows you to monitor systems. Works with NT server only. Desktop management, Remote Control, software distribution, Inventory management (hardware and software data).

Q13:- What is network data security?
Ans:-Network Data Security
Password Protected Share (share level security) – assign password to each shared resource
Access Permissions (user level security) – user enters a logon and password at login and server checks a database and assigns security as applicable. Resources are controlled by the administrator and are allowed to the user at login.
C2 compliant – Govt. level of security
Virus checks, passwords, access rights.

Q14: what is RAID?
Ans: RAID (redundant array of inexpensive disks) – Fault Tolerance
RAID is handled through NT’s disk administrator. (Supports 1&5)
Level 0 – Disk Striping – divides data into 64K blocks and distributes evenly among all disks in an array. Provides no redundancy or fault tolerance.
Level 1 – Disk Mirroring – Write all data to two hard drives in sync, if one fails then swap.
Level 5 – Disk Striping with Parity – supports three to 32 hard drives. Allocate same amount of space on each hard drive. Divides data into 64K blocks and writes parity info evenly among all disks in an array. If one disk fails, enough parity info is written across other disks to recreate it. Parity stripe block is used to reconstruct data.

Q15: What is MODEMS?
Ans: MODEMS – converts digital PC signal to analog phone signal and back. Uses sound waves to transmit data. Telephone lines have a 33,600 Kbps max speed.

Ans: X.25 protocol – incorporated into packet switching network. Uses PAD. – Packet switching protocol.
PAD – packet assembler/disassembler – receives asynchronous characters from terminals and assembles into packets to be transmitted over network and back.
Frame Relay – point to point system – uses PVC – fast packet, variable length digital – digital leased lines. Provides bandwidth as needed. – Packet switching protocol
ATM – asynchronous transfer mode – fixed packets – broadband.
Speeds up to 622 Mbps – used mainly for ISP backbones because of cost.
