Virus Issue, Scan the Workstation by using antivirus,delete the Temporary file, cookies, History, Clear Cache,
On browser, Run less, Website.
Check the Patch code, crimping, I/o port crimping.

Check the network connectivity, check the traffic, check server from which user's workstation is requesting data

UDP is connectionless because it does not initiate with a three-way handshake. It is least concerned about whether destination received data or not.

In Transport Layer,
Two Way Communication,
Connection Oriented.
Connectionless
Connectionless is Used For Small Distance,
It is not reliable for big betwork, No Ack Received, No security

We assign two IP address in the Network for any Workstation.
For security, means to true Identity/

You can assign as many as IP Address to XP machine as much as NIC you have installed in your machine.

you can also team the NIC and assign single IP address to configure network traffice balancing for that particular machine's incoming or outgoing traffic requests.

IP address 8 Bit address is divided into Network and Host,it is used to communicate into Network.
MAC address is 48 bit address and it, is a Unique address, Just like two ethernet card not having same MAC address, is not used in Network,only Physical Layer is used by this address.

IP Address is the Address of a network which is given By network InfraStructure but MAC Address is already give on LAN Card Chip and it is not changable.

RIP (Routing Internet Protocol) is used for Classless routing.

Classless routing is the type of routing in which we can forward the subnetted networks.The different types of routing protocols that support classless routing are 1)OSPF (Open Shortest Path First)2)I...

Split Horizon,it is a ,away or method to avoid the Routing Loop,It generally happens in LINK State Routing Protocol, means Router Send the update or any information to another Router those receiving router does not send the
information back to sender router

Check the Driver of Ethernet card,
Check the Patch Code,
Check the Connection from I/O Port to LAN Port of Laptop,
Check the TCP/IP Configuration,
Repair the TCP/IP,
Check the I/O port,
Check the Pairing Of Patch code,
Check the Connectivity From Switch to I/O Port,
In Extreme Case check the Router.
