Help!

When I was at the Heritage, one had to login via their Intranet. And it directed me to get.in2.net which took me to heritage homepage.

Now whenever I type in www.kiwiblog.co.nz (set as my homepage) it tries to go to get.in2.net. Only happens in Firefox and only for that exact URL. I have rebooted machine and it is still doing it. Am back home now.

Anyone got any suggestions for how to fix this very annoying problem?
