From: aa on 29 Oct 2009 01:34 is there a way to change physical address of Ethernet Adapter which shows up in ipconfig /all like 00-11-2F-00-11-2D ? My Internet provider uses this address to set something on their end manually. For the moment I am testing another computer and every time I switch between the two computers I have to call the provider

Device Manager Select your NIC In its properties, change its network address.

Maybe what you want, is "MAC address spoofing". That is a way to get a computer to have the same MAC address as another. Obviously a bad thing to do, if both computers are hooked together to the same networking device. But if you're swapping computers, and the other computer isn't being used, then spoofing should be OK. (The MAC address may be part of Windows activation, and I don't know whether spoofing counts as "one hardware change" or not.) http://en.wikipedia.org/wiki/MAC_spoofing http://www.klcconsulting.net/smac/ I don't have a cable modem, but I understand that some ISPs use the MAC address as some kind of authentication. Normally, to avoid a situation like this, you'd connect a home router to the cable modem, and the router, having a fixed and unchanging MAC address, allows you to connect computers on the LAN side of the router, without worrying about stuff like this. With this setup, I wouldn't need to phone anyone. cable_modem -------- router ----- home_computer_#1 (fixed ----- home_computer_#2 MAC) ----- etc HTH, Paul
From: Meinolf Weber [MVP-DS] on 29 Oct 2009 03:25 Hello aa, There is no need to change a MAC address in your computer. MAC addresses are unique all over the world, depending on a company code and the internal numbering of the company. I have never heard that an ISP uses MAC addresses from clients. Please be more specific what your problem is and also talk to your ISP to free the MAC address, if this is really used from the ISP, which i can not really believe.

As others have said it is somewhat strange that your ISP would be using your adapter's MAC address to deliver its service to you. If that is truly the case then install a router and your problems will be over, the ISP will use the router's MAC address and you will be able to connect/disconnect whatever you want into the router. If you have a half decent router you can even tell it to adopt the MAC address presently in use and your ISP will be none the wiser for it.
