Windows System Error - IP Address Conflict??
 

Greetings Everone,
As of late I have been getting this yellow popup in my taskbar stating, "Windows System Error - There is an IP address conflict with another system on the network." I can't think of why. A new roommate made in in August and that was the last computer added to the network. I don't know why its happening now all of sudden. Is there a way to fix this and stop the popup and or problem? Thanks

are you using dhcp or static ips? if static, make sure one of your room mate's hasn't changed their ip to yours lately, that could be causing the conflict. if you're using dhcp, try running the windows network connection repair thing (available by right clicking on the local area connection icon in the control panel and clicking repair). also, make sure if you're using dhcp that whatever is providing the dhcp service has permission to supply enough ip addresses for every computer on your network. hope this helps (more information about the hardware involved would make the problem easier to troubleshoot)

We are using a Linksys WRT54G Router. When I access my router is says we are using Automatic Configuration - DHCP. Under the maximum number of DHCP users it is set at 50 and I we have 4. I apologize for not adding this in my original post but I always forget to add my hardware. Thanks for any help.

then set them to static IPs if there is only 4 of you.

I would guess that your wireless router is not properly secured and you have a neighbor 'borrowing' your service. do a search for Mr Mephisto's posts and you will finds some great information on how to secure your wireless router including using WEP or WPA, turning off broadcasting and using MAC authentication.

Type "ipconfig/all" from a command line (if in Windows) on both machines to find out what IP address they have.

Try "ipconfig/release" and then "ipconfig/renew" and see if they get the same IP address.

oiekeooiyw has a good point. Using static ip's, as bendsley suggested, is far more secure for wireless, and you definately don't want 46 unsecured but usable ip's floating around your neighborhood. It takes no talent and very little time to compromise an unencrypted wireless network.
