IP Conflicts in a work place

An IP address conflict occurs when two computers on a LAN or the Internet have been assigned the same IP. IP conflicts between two computers normally render either one or both of them unusable for network operations.

How IP Address Conflicts Happen

Two computers can acquire conflicting IP addresses in any of several ways:

· A system administrator assigns two computers on the LAN the same Static IP Address.

· A system administrator assigns a computer a static IP address within the local network's DHCP range (dynamic IP range), and the same address is automatically assigned by the LAN DHCP server.

· A malfunction in the network's DHCP server allows the same dynamic address to automatically be assigned to multiple computers.

· An ISP accidentally assigns two customers the same IP address (either statically or dynamically).

· A mobile computer is put into standby / hibernate mode and then awakened later.

Note that other forms of IP conflicts can also occur on a network. For example, one computer may experience an IP address conflict with itself if that computer is configured with multiple Network Adapters. System administrators may also create IP conflicts by accidentally connecting two ports of a network switch or router to each other.

Recognizing IP Address Conflicts

On most Microsoft Windows computers, if you attempt to set a fixed (static) IP address that is already active on the local network, you will receive the following pop-up error message:

The static IP address that was just configured is already in use on the network. Please reconfigure a different IP address.

On newer Microsoft Windows computers having dynamic IP conflicts, you should receive a balloon error message in the Taskbar as soon as the operating system detects the issue:

There is an IP address conflict with another system on the network.

Sometimes, especially on older Windows computers, a message similar to the following may instead appear in a pop-up window:

The system has detected a conflict for IP address...

On Mac or Linux computers, a similar message will normally appear on screen.

Resolving IP Address Conflicts

Try the following remedies for IP conflicts:

1. For networks where IP addresses are fixed (statically assigned), ensure each local host is configured with a unique IP address.

2. If your computer has a dynamically assigned address, releasing and renewing its IP address can workaround IP address conflicts.
3. If your home router is believed to have a faulty DHCP server causing IP conflicts on the home network, upgrading the router firmware may resolve this problem.

Acer 4720z wi fi driver on xp Os

Hi There, since Acer do no release a wlan driver for Windows XP, you need to use the driver for Window Vista. If you do not have the driver for Windows Vista, you download it from here . After finish downloading, then un-zip the file. Now let's start to install the wlan drivers. Go to your "Start Menu", then "Settings", "Control Panel" then "System", system properties windows will be pop up. Then select "Hardware" tab, and then click on "Device Manager" button. You will then see "Device Manager" windows. Look for your "Network Adapter" and you will see your wlan network adapter with red cross mark.Right click your red crossed wlan adapter, then select "Update Driver"
You will prompted with "Hardware Update Wizard" then select on "No, not this time" radio button and click on "Next" button. On next windows, select "Install from a list or specific location (Advanced)" radio button and then select "Next" buttons.
Then another window will pop up, then select "Don't search, I will choose the driver to install", then click on "Next" button. Then you will come to this windows "Select Network Adapter", you will see you existing network adapter that do not working, then select "Have Disk", and browse to the location where you have unzip the driver. Then Select the appropriate driver for your laptop. Acer Aspire laptop 4720z come in 3 wlan varian, Intel chipset, broadcom, and Atheros and I don't know which one is on your laptop. Just try one by one if you are not sure, it's only 3 to choose from.
Hope my solution could help you out.

Acer aspire 4720z audio driver for widows xp home edition sp2

Have you gone to the acer site? and second question I too have an acer and I got rid of Vista is this what you did or did the computer come installed with xp. If it did make sure you have the Microsoft hdd coded driver installed. It is available by googling "hdd audio driver" it will send you to microsoft to download. Also make sure you have completely deleted the previous software before loading the new one they will conflict and load on top of each other. Hope this helped..Take care.. Be mucho blessed..Mark
