MAC address

[zmerlinz]

does anyone know of any software that would change the MAC address of a network card to be a different one ??

[parksie]

There's a registry key you can change in Windows to do it:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Net\0000

Add a new string value "NetworkAddress", and give it a value of the new MAC address.

[parksie]

Make sure you pick the right number, not just 0000.

Q. Is it possible, in any way, to change my MAC address? If so, how would I do this?

A. First, it helps to know just what a MAC (Media Access Control) address is.

This is a numeric identifier built into a network interface card, or NIC. It's used to identify devices on a network. Each card has a unique MAC address, and networks (including the Internet) can use this for authentication and verification of any PC or router attached to it.

Some broadband Internet providers offering DSL or cable-modem access will use the MAC address of your computer to authenticate your service. If you were to change the computer you have connected to your cable modem or DSL service, you may have to call up your provider's tech support and give them the MAC address of the NIC in the new piece of hardware.

Because hardware routers have the equivalent of a network card in order to connect to your cable modem, you would have to do the same thing if you're installing a router. So far this does not appear to be true of Road Runner here in Houston.

However, some providers have started to recognize the MAC addresses of popular routers and disconnect service if a router is detected. Fortunately, most of the popular DSL/cable routers include the capability to either set the router's MAC address to anything you want, or copy it from a computer connected to the router.

You can find your computer's MAC address by using the winipcfg command in Windows 95, 98 or ME (Start, Run, winipcfg); the ipconfig /all command in Windows NT and 2000 (Start, Run, CMD, then ipconfig /all); and the Info Button on the TCP/IP Control Panel on a Macintosh.

Look for "Adapter Address," "MAC address," "Hardware Address," or a string of six pairs of digits and letters, such as: 00-02-A4-03-43-60.

Some network cards have the ability to change the MAC address through software. If your card and driver support this feature, you can change the MAC address under Windows 2000 by doing the following:

• Use Control Panel and double-click Network and Dial-up Connections or Start/Settings/Network and Dial-up Connections.

• Right-click the connection that uses the network card and press Properties.

• Press the Configure button.

• Select the Advanced tab.

• Select Locally Administered Address.

• Enter the new MAC address value.

In all likelihood my Houston readers should not need to change their MAC address, but you never know if this will come in handy down the road.

does this also work in 98 do you know ??

and what do you will happen if two computers on a local network have the same mac address

[parksie]

That's the address for 98, I assumed that's what you wanted since NT can do it from the control panel (as tt2 said).

I don't know what happens...it probably won't work

[zmerlinz]

thanks a lot for the help here, it was greatly appreciated

[parksie]

Pas de problème

[thinktank2]

how do u guys type something like è ? which keyboard key does it replace ??

[parksie]

I just used Alt-0232.

[chrisjk]

some key-combos produce those letters without the need for ALT+???, like

CTRL+ALT+E = é
CTRL+ALT+SHIFT+E = É
CTRL+ALT+A = á
CTRL+ALT+SHIFT+A = Á

etc

[Wally Pipp]

I have a multifunctional keyboard directly connected to my synaptic pathways.
I think the characters, therefore I virtually am.

i just press altgr and a vowel and then it is accented

áéíóúí

[parksie]

Ah

Mine does that as well áéíóú

What is altgr?

[parksie]

It's on the right of your space bar

[chrisjk]

actually it's an alternative to let your Windows know how pissed off you are when doing ctrl+alt+del

If you do ctrl+alt GGRRR!!! +del then it knows you are very annoyed and will try it's best not to do it again

[Gandalf_Grey_]

no no no filburt if you presss Ctrl Alt GRRR Del then windows knows you are pissed off however bieng windows it will be sure to do it again

[chrisjk]

no no no filburt if you...

Interesting theory, but i think you'll find I ain't filburt and may have to take drastic action to ensure this doesn't happen again

[lord_dude]

Why would you want to change a MAC address? I thoght the whole point of a MAC address is you dont have to piss about with them to make sure you dont have conflickting address and stuff coz they are all unique?

[steve65]

Some ISP's require you to have a certain MAC address that is assign to a NIC card that they gave you and then they give out an IP address only to that MAC address. This way you can have only one computer hooked up to their network. Most routers now have the ability to change their MAC address to the same as the NIC card so your can put your whole network on the internet.
