WINDOWS 2000 NETWORK PROTOCOLS
Win2K supports 3 Protocols by default:
1) TCP/IP (installed by default windows)
2) NetBios
3) NWLink
1)NETBios:
- Advantage:
-- Small and compact Protocols
-- Fast
- Disadvantage:
-- Not Routable
---- Only usable within one LAN
2) NW Link: (NOVELL WINDOWS LINK)
- Microsoft implementation of IPX/SPX
- Novell standard protocol
3) TCP/IP
- Transmission Control Protocol/Internet Protocol.
- Default Win2K Protocol.
- almost exact opposite of NetBios.
- High overhead.
- Routable between networks.
- Not vendor specific (understand by mac, linux, unix, windows)
NetWork Bindings:(single adapter with multiple protocol)
- Order protocols are used
- If Muti-NIC, Binds order NIC will be used.
- Put most used protocol on top of bind order.
NIC 01:
|_NetBios
|_NWLink
|_TCP/IP
TCP/IP Protocol Stack:
- HTTP, FTP, DHCP, PPTP, SMTP, ARP/RARP, DNS, WINS, LMHOST, HOST, NBT, TFTP, Telnet, UDP, TCP, IP, ICMP...
Name Resolution Protocol:
1)- Mac Address (in order for computer to talk one to another)
-- ARP (Address resolution protocol) takes IP address and resolve into MAC address.
-- RARP (Reverse ARP) takes MAC address and resolve into IP address.
2)- NETBios Computer Names
-- Local network computer name.
-- Resolve NetBios name into IP address.
* WINS (Windows Internet Naming Service)
- Dynamic Name Resolution.
* LMHOSTS
- Static Name Resolution.
3) HOST Name Resolution
Host Name and Computer name are the same. Within NETBios it's call computer name and within Internet (TCP/IP), it's called Host name.
- Resolve Host Name into IP address with following 2 methods:
a) DNS (Domain Name System)
- Resolve FQDN (Full Qualified Domain Name) into IP Address.
I.E. Our Domain Name is ZEUS.NET2001.Com (FQDN) and ZEUS is host
- Dynamic Resolution.
b) Hosts File:
- Static
Internet (TCP/IP) ** LAN (NetBios)
DNS ---- HOSTS ***** WINS ------ LMHOST (all resolve computer name into IP address and use ARP to resove into MAC address)
HTTP (Hypertext Transfer Protocol)
How we become DHCP Client:
From command Prompt: type ipconfig /all
My Network places and Properties
- Web pages use HTTP.
FTP
- File Tranfer Protocol.
- uses TCP (Transmission Contro Protocol) reliable protocol and have error correction.
TFTP (Less stable than FTP)
- Trivial File Tranfer Protocol.
- uses UDP (User Datagram Protocol) connectionless, no dilivery guarantee.
DHCP (Dynamic Host Configuration Protocol) really good but if setup incorrectly then the whole network will be down.
- Server automatically assign TPC/IP info to Clients. (IP address, Win server, Time to live, etc.)
PPTP - Point to Point Tunneling Protocol - use for VPN
- Creates a "Virtual" Private connection through internet. (must use a private line)
SMTP (Simple Mail Transfer Protocol)
- Email
NBT - NetBios over TCP
Telnet - terminal Emulation Utility
- allows one computer to telnet to another computer for control
ICMP - Internet Control Management Protocol - use to trouble shoot the network (ie. Ping, Tracert)
Set HDCP: from Network and Dial-up Connections right click and properties on Local Area Connection and properties on TCP/IP then select Obtain an IP address automatically.
