Because windows is flawed, my computer dose this some times, even
though I donâ??t unplug any thing (often iâ??m not even at home when
this happens), it will suddernly decide it is no longer connected to
my DHCP server and gives itâ??s self a IP address, whcih causes me
grate anoyance, the only way to stop it from doing this (or so it
seems) is to stop the DHCP client (windows service) after you have
initaly contacted the DHCP server.

Windows, unlike Linux, will constantly try to keep incontact with DHCP
servers (unless instructed other wise), where as Unix base systems
only quiry the DHCP server once (unless instructed other wise by the
user), and then just asume every thing is OK, which windows should do,
but dosnâ??t.
