I've been having trouble with my laptop rebooting. I went through the shutdown troubleshooter & figured out that what is causing it to hang up has to do with dhcp. I then looked at the event viewer & got this message: The address IP lease xxxxxx for the Network Card with the network address xxxxx has been denied by the DHCP server. Does anyone know what I can do to fix this?? I am running Windows XP & am on a wireless network. Thank you!
