I have 2 computers networked together and normally there is no conflict however I got this message on one of the computers "The system has detected a conflict for IP address 192.168.1.101 with the system having hardware address 00:11:09:A2:60:73. The interface has been disabled." And the computers can no longer "talk" to each other...please help I'm not a techie a do not understand what the error message means.

could be just a glitch with dhcp. reboot both pcs and see if it self corrects.

The error message means that two computers are set to the same IP address. And IP address must be unique to each computer (or any device) on the network. The error is saying the two devices, computer, printer, router, have the same IP address. When this is detected, the second device to try to use the address will be disabled. As wanderer said, it is certainly worth a reboot to see if the problem goes away. DHCP should know better than to hand out the same address twice and will generally check to see if an address is in use even if it didn't hand it out originally. If the error returns, you'll have to track down the device that is causing the conflict and change it's address. Good luck.
