2 computers have the same IP address

1st find the two computers or items that have the same IP address by following the step to get to the command prompt on computers and laptops. If one is a printer you'll need to go into the network settings to look. Pick one and go to the start button and on the start menu find the run or search and type "cmd" and hit enter. This will open the command prompt window. Type "cd\" to get back to the root (c:\>) now type "ipconfig" and hit enter look at the IP address and make a note of it, next type "ipconfig /release"(leave a space after ipconfig) and the computer will wipe the IP Address, next type Ipconfig /renew (leave a space after ipconfig) and it will pickup a new IP Address. check if it's the same or different from the one before. If it is different you are done.

what does computer command "ipconf/release" do?

This command will flush the IP address from an active connection. The correct syntax is ipconfig /release *con* which will release all connections. If you just want to see if you can get a new address then use ipconfig /renew

Intermittently, my home network and internet access ceases to function. Troubleshooting indicates the "Local Area Connection" doesn't have a valid IP connection. Resetting the router (12 second power disconnect) resolves the symptom. How do I fix the problem?.

Going inot the router configuration page and reserving your computer with a specific IP address would resolve this issue, If you have never gone into the router config page, it would be reccomended that you not do this, and have a computer savvy person with networking experiance do this for you.

another solution would be releasing and renewing your IP address in the command prompt on your computer

in command prompt, type : ipconfig /release ENTER then ipconfig /renew to renew your ip address, this can be done rather than resetting the router everytime

need to renew ip address for my emachine T3516

just right click on your local connection on the desktop by the clock and click on "repair". this should clear the cache and renew the IP addy and DNS for yur connection. OR

Follow these steps to quickly release and/or renew the Internet Protocol (IP) address of a computer running Windows XP, Windows 2000, or Windows NT. Here's How:
  1. Click the Start menu button on the Windows taskbar.
  2. Click Run... on this menu.
  3. If the computer is holding a current IP address, type 'cmd' (without the quotes) in the text box that appears. A command prompt window appears on the screen.
  4. Type 'ipconfig' (without the quotes) to view the status of the computer's IP address(es).
  5. If the computer is holding a current IP address, type 'ipconfig /release' to let go of the address.
  6. Type 'ipconfig /renew' to obtain a new IP address (whether or not the computer is holding a current address).
  1. If it is not necessary to view the current IP addresses on a computer, simply type 'ipconfig /release' or 'ipconfig /renew' (without the quotes) in the text box that appears in Step 3.

  2. To bring a computer back onto the network after moving it to a different location, or experiencing an unexpected outage, first release, then renew the IP address. Computers on DHCP networks often (but not always) re-establish network connectivity automatically
