IP address conflict

[anon]

Cross-posted here as I did not receive a response in the other ng.

What does the error below mean and how do I fix it?

(BTW the other computer connected to the router is off.)

It has just recently appeared. There has been no change in the 'network'
itself.

Error: "There is an IP address in conflict with another system on the
network".

This error appears when I wake up the computer after it has been off long
enough for the screen saver to turn off and the on/off switch light is
blinking.

Actually you're not cross posting...you're multi posting. You'll get better
results if you cross post to the relevant groups. Cross posting is sending
one message to several newsgroups at one time. Multi posting is sending the
same message several times to several groups, one after the other. A reply
to a cross posted message will hit all the newsgroups you posted to but a
reply to a multi posted message will hit only one group.

How is the router used to control the network?

Is it using DHCP?

Have you assigned IP address directly into the TCP/IP connection of each PC?

Have checked fore driver updates recently, especially for the network adapter?

Is this a laptop? If not, you may want to consider disabling hibernation /
suspend, so as to diagnose this problem.

network".

It means that your router assigned your computer an IP address, then yours
went to sleep to the point that the router felt it had left the network and
assigned the IP address to another system. When yours wakes up, it tries
to use its assigned address without checking, and detects the conflict.

You need to get a new IP address from the router or prevent the router from
reassigning the old one.

This error appears when I wake up the computer after it has been off long
enough for the screen saver to turn off and the on/off switch light is
blinking.

Immediately, this pair of commands from a command prompt window should fix
the problem:
ipconfig /release
ipconfig /renew

If you save those two lines to a text file, save it on the desktop as
reset_ip.cmd, you can run it anytime the problem occurs and it will fix it
for the moment.

However, that does not address the question of why the router thinks your PC
has left the network and why it's reassigning addresses. One of the things
that can cause this is power management settings turning off the network
adapter to save power, concurrent with other sytems joining the network.

If you think your router doesn't have any other systems connected to it - if
it is a wireless -capable router, you might want to check the DHCP logs as
other systems you don't know about may be using it. Change the passwords
and the encryption keys.

Will try the commands but how do I know that the commands DID anything?.

The error message goes away immediately when I click on it.

The error has only started in the last few days and no change has been made
in the network.

The error shows up on the desktop computer and the other one is a notebook
computer.
