    Say I was on an internal network, controlled by a central server, about 10 computers, all with different 'internal' IP addresses.

    Is there any possible way to mask a different computer's IP address, and make the server think I'm actually the other computer? Without getting the whole 'there is another computer using your IP address?'

    The network I'm talking about has each computer connected to the internet, but each internal IP address is assigned different rules. Some have unlimited internet usage because they get their work done in time, more or less, others have more restrictions because they spend too much time at certain sites, and not enough time doing their work.

    ....just wondering here.

    Turn off the target computer, set your IP address manually to its designated IP address. This may or may not require changing your DHCP client ID.

    Yeh well, that'd work if the network isn't using MAC addresses to keep track of the IP assignments...

    But even if it worked, as soon as the other user powered on, HE would get problems, so your cover would be blown quickly.

    If it makes you feel better i'm still trying to get Xp and Vista to talk to each other on a network.

    Would have more luck trying to hammer nails with my cock.

    Turn of the other computer and change your MAC address. This is easy enough in XP through the device manager (find your network card>Properties>Advanced>MAC Address, IIRC). No idea how to do it in Vista.

    Screwdriver in the other guy's power supply.

    I do that all the time, it's not so difficult. Unfair comparison to getting Vista and XP to talk to each other.

    One of these days I should get a hammer....
