XP checks intranet for local files first

Hi,

I have a laptop with Windows XP which is registered as a computer in a group

on the intranet at work. When I try to open a local file, XP checks the

intranet first. This is OK at work. But at home with a wireless connection

to the internet, when I try to open a local file, XP tries to check the now

nonexistent intranet and the delay in opening a local file is nearly a

minute before it times out and the file is opened. Is there a way to alter

this behavior?

Thanks,
