Which utility enable you to reset a computer's network adapter?
IPCONFIG is one, and it is a part of Windows 2000-Win7. In the
run box or the command console you would first do:
Ipconfig /release
Then you would do:
Ipconfig /renew
If you have Windows 95/98, the equivalent would be WINIPCFG, and
it is in the form of a GUI, so you would click on the release or
unbind button and then on the renew or bind button.
