Reclaim a Hijacked IP address?

[turkster]

I live in an apartment which includes free internet access through the local Institute of Technology. (Student Accom so they get tax relief but have to have free internet). This gives massive bandwidth often around 1 Mbytes a second and the whole apartment is prewired so its pretty cool.
Anyway the apt blocks are connected through a gateway and we all get assigned seperate IP addresses. This morning i booted up my brothers comp which hadnt been on for a week or so and i was faced with the warning message saying that the was a network conflict with this IP etc.
Now this isnt really a problem as there are three IP addresses assigned to our apt and normally two of the comps are networked together and use ICS so we have an IPaddress spare but this could have been rather annoying especcially manager/agent does not understand such things.

I was just wondering if there is some way of reclaiming the IP address shortof rebooting untill you catch that IP unused and then leaving your machine on?

find out who owns it and go talk to them, failing that ask the people that administer the network for some more IP's?

Or ask them to change it to sticky DHCP so that when someone adds in another device it just auto assigns another ip from the block

net send them and ask them to restart so you can get it back.


failing that, why dont you just call your university IT helpdesk?

Well the problem is that IPs are individually assigned to each apartment and we are meant to use specific Computer id etc so they know who's on which IP etc. Going to network admin or management would be very slow anyway.

It is only a theoretical question as it is not a problem at the moment but thanks anyway.

How do you do that! I'm a bit green on this networking thing!

go to start and click on run.
type in cmd
hit enter, should get a black dos box
type: net send 192.168.0.1 (obviously with the IP your trying to net send to) whatever you want to say
so long as he doesnt have a firewall and has the message service running he sould get it and there will be a message confiming he got it, it will pop up a message box on his screen.

Thanks for tip. Does that not work on Win 98 as it doesnt seem to. I havent got an Xp system to try it on at the mo (my main system is awaiting new RAM).
