is there a way to spoof a computer name on a wifi network? there is a lot of tools for mac adresses but none for this.

I know i could change it by rebooting but I don't want to have to reboot.


example of the view from my router : enter image description here

    It's trivial to change a computers name. – Ramhound Dec 10 '13 at 20:53
  • I don't change it because it requires a reboot, I want to appear with an other computer name on the network – sliders_alpha Dec 10 '13 at 20:54

    There is no such thing as a "computer name" on a network. This is way too vague. – BatchyX Dec 10 '13 at 20:55

    You asked if it was possible to spoof the computers name the answer is you don't need to spoof it just change the name if the computer. What problem are you trying to solve where your required to have a certain computer name? – Ramhound Dec 10 '13 at 20:57

    Are you sure that blacklisting is really by computername, and the router is not just giving you a friendly name tied to a MAC address? – heavyd Dec 10 '13 at 21:02

Ultimately the answer is no.

The way computer names function on a network they are registered with the next in line DNS server (usually a router). Not to mention you'll most likely not be able to even get the OS to change to the same name as when you go to change your computer name your OS will surely throw some NetBIOS error that the name is already in use.

So spoofing a computer name itself is not technically feasible. When you change the computer name of the machine you're on (for whatever reason) the DNS server that the network is talking to is going to continue to serve information to the original computer because the computer you're on was not able to register as that computer name. If you're looking into some higher level of IT tomfoolery then look into "wifi man in the middle" tools.

  • I found a way to hide it, if done while disconnected from the router and while also changing the mac adress then the router will give you a random computer name, allowing you to get through the routeur blacklisting – sliders_alpha Dec 10 '13 at 21:46

    command is "net config server /hidden:yes" to hide your computer name. command prompt should be runned as administrator – sliders_alpha Dec 10 '13 at 21:47
  • @sliders_alpha That's a weak method of blacklisting of that modem ;) – Rik Dec 10 '13 at 23:14
