Dear friends,
Did u know that mac addreses of many PC's can be changed

Visit:
*www.nthelp.com/NT6/change_mac_w2k.htm


But remember Not all LAN's hav the Mac address property.


LANCER and Tech com were the companies who provided this property earlier
This property is no longer Available with the LAN's Of Today.

U got it all wrong Mr invisible, Not every Lan has that Property (mac address Property) but has a unique 48 bit mac address assigned to it which can be changed easily changed using Network or mac address property.
Hope u got it


Proof:
Check out whether u can change the mac adress of Pc's in our Coll\ office, i bet will surely find one Pc atleast which wont hav that property
Generally Motherboard having INBUILT LAN wont hav that property.


And BTW with "This property is no longer Available with the LAN's Of Today" is meant that lans manufactured nowadays(recently) wont hav that property for security reasons



i never meant that Mac address cant be changed if that property is absent
using Smac everthing can be done

i emphazied on how easy it is to change tha mac if the Lan itself has that property, no need to use snooping soft(Smac).
if its isnt available(property of mac address), then smac is handy but risky.

What is with u all, guys? Y cant u understand such simple things
Let me make it simpler


u can change ur mac address Via Device Manager(i dont deny it)
Rite

Now consider the case wherein ur Lan card is damaged, and u are forced to buy a new one.
Now with the New one u cant change Mac Via Device manager
bcoz u wont find that property of MAc or Network Address
Remember, whether u can change the MAC or not , depends on the LAN and Not the OS.


Dont be under the impression that one can Change the MAC Address of all the PC's Via Device Manager.
U all Can bcoz ur Lan Card Supports that property

Try Changing the Lan Card or Else Try It With Some other PC's


I could change my MAC Before but not any longer After i bought the New Lan.

Thats not true... It solely depends on the LAN card manufacturer, and the driver, not on new/old cards... I bout a card a week back, and i can change the MAC address via device manager.

Anyway, why such a fuss on changing MAC address via device manager?? Everyone knows there are tons of utilities to change MAC address!

Ok, the confusion seems to be not knowing what mac spoofing is. The mac address stored on a rom in your lan card is not changeable. When you are mac spoofing, only the OS's view of the address is changed. It absolutely does not depend on the manufacturer/date of manufacture or onboard/external lan card. As long as the OS allows it, it can be done. Even if it doesn't you can probably reshack it, I guess.

To change the MAC Address Go To
My Computers->Properties->Hardware->DeviceManager->NetworkAdapters
Right Click on your LAN card.Then Go To
Properties->Advanced->LocallyAdministeredAddress
Check the option of your value and enter a 12 digit Hex Code
Sometimes some companies have some rule about the starting letters of the address so the best option is to change the last few digits of your actual MAC address

Y dont u read the forum properly
The discussion here is not how tho change Mac address, but the discussio is about some Lan card which wont have the network adress property
so one cant change the Mac adress in the Way u mentioned obove
In these Lan's u wont Find any thing called as " LocallyAdministeredAddress Or network add or Mac adress( depends on manufacture)" . so One cant change the maC ADDRESS

Though using Softwares it can stil be done even if the Foresaid property is absent.

Once again Requesting u to read the posts Carefully and then Answer

Chill, guys.

I think what Andyiz is trying to say is that his comp's NIC (network interface card; calling it *LAN card* is too crude IMHO) doesn't have the property to change the MAC address via the windows device manager i.e. does not allow MAC spoofing via the device manager.

Although I have personally not found any card which doesn't allow the change, some chipset manufacturer(s) might have disabled the property. AFAIK and as evident from previous posts, we can always use 3rd party apps to spoof the MAC.

Hope invisible will get andyiz point now. Andyiz, i know it's frustating when people don't understand what you are trying to say but the key is to remain calm and try to be as clear as possible.

Peace.
