From time to time I get this Network Error message. There is only one computer on 'this network'.
The relevant System event log items states "The system detected an address conflict for IP address 192.168.0.100 with the system having network hardware address 50-1A-C5-22-F3-64. Network operations on this system may be disrupted as a result.". Not being a tech guru, this is more-or-less gobbledygook to me.
Given the general risk of "nasties" invading the computer should I be worried?
If you do have more than one device as suggested then 1 device might have a static IP address and the other device may have a dhcp address. As the static address is hard coded and the dhcp address is auto assigned then they may clash if the dhcp IP address is the same as the static address. If so, change the device with the static address to get its IP address via dhcp. That way the dhcp addresses will be managed.
Nothing to worry about, it is something that pops up on my laptop every so often. Being in a household with two computers directly connected into the router, 3 iPhones, 2-3 iPads and 1-2 laptops all fighting for connections, sometimes double ups occur, especially when they're rarely all connected at the same time.
To help resolve it, open up the "Network and Sharing Center" on
your PC.
In that dialog, click on "Local Area Connection" and a "Local Area Connection
Status" dialog will pop-up. Click on "Properties".
Another dialog will appear. Double click on "Internet Protocol Version 4 (TCP/IPv4").
Another dialog will pop up. Under the General Tab, ensure "Obtain an
IP address automatically" is selected. Under the Alternate Configuration
tab, ensure "Automatic private IP address" is selected.
If all devices are configured correctly to obtain IP addresses dynamically,
you should never see an IP address conflict.
There are a few times I have seen however that a static IP address is better. We have a NAS at home that serves all our files and has all our media stored on it. Windows seems slow to re find it after an IP address change so static IP is better for that device. But if you set up static IP addresses, set them up in your router and leave the device you are assigning a static IP to using DHCP. That way the router will reserve that address and hand it out to the device every time, rather than trying to assign it to something else.
Very many thanks to all for replying so quickly. Your replies are much appreciated.
Nikolas : I'm not too sure what is meant by “network”. I have not deliberately set up a network having only one computer hard wired to the modem. But reading the replies received I get the impression that a “network” can involve other devices that are indirectly connected to the modem via a wireless router. If so, then I do have an indeterminate number of networked devices. In addition to my main hard-wired desktop the other indirectly connected devices can include the observatory laptop, my iPad, a daughter's personal laptop and a variable number of iPhones and iPads used by grandchildren and their friends.
Damien : I would try if I could understand what to do but given my lack of tech expertise that's not likely.
Colin : Your reassurance is comforting.
Gary : I did as you suggested and found that indeed the stated selections were already active in the “Network and Sharing Center”. As to whether all devices are configured correctly to obtain IP addresses dynamically, that I don't know and I don't presently understand how I can check to see.
Paul : I've no doubt that you are right but setting IP addresses is presently a bit beyond me.
In summary, I think that I'll shelter behind Colin's reassurance and hope that my failure to take the active steps suggested by others due to my lack of tech expertise will not result in disaster further down the track.
My understanding of it is that your computer had an IP assigned to it by the router, if your computer goes to sleep for a while that IP address within the router then becomes fair game for a new device, lets say a phone connects to the network and is given the IP that your computer used to have. When you wake your computer up if it decides to connect via the IP that it had been previously assigned without requesting a new IP, it'll get a error message saying that the IP is currently in use by another device.
Cause for concern?
