on Windows XP?

guy at my work had comcast at his house setting up internet and the comcast guy could not get his laptop to see the IP address coming from the modem. I know usually you can just shut the computer down and restart it and it works.....but in his case the old IP address on his laptop will not go away....is there a way to manually clear it?

go to the command prompt and type

ipconfig /release then

ipconfig /renew

hope that helps.

sounds like it may have been assigned statically.

right click on 'my network places' and select 'properties'.
highlite 'tcp/ip' and click properties
if 'use the following ip address' is selected, clear it along with the subnet mask and default gateway.
you may want to write that info down first in case you need it again.

i've had that same problem with comcast and my laptop. If its dhcp then the computer is borrowing that address for a specified amount of time, cable is usually static though, Just like above, you can manually enter the address or chose to let dhcp assign the computer one. It could be a firewall or something blocking it as well. Is he using a router?

regarding brendan's post, you can also go to Network Connections and click Repair in the context menu, and in addition to renewing the IP it'll flush the cache for the DNS, ARP and NetBIOS and other things... but the Comcast guy probably tried it a few times already and I'd take the route that XWHISKEYX suggested and set it to DHCP if it isn't already.
