Well I'm using a laptop and I plugged in the ethernet cable from the computer that isn't working and the internet was working fine.
When I tried the release/renew thing I get:
"Windows IP Configuration
An internal error occurred: The request is not supported.
Please contact Microsoft Product Support Services for further help.
Additional information: Unable to query host name."
EDIT: I also tried the method described here http://www.geekstogo...amp;hl=ipconfig
to rename tcpip.sys to tcpip.sys_old but my computer didn't give a warning like it did for the guy who talked about this method. So then I used my XP cd to reinstall the tcpip.sys files but it didn't do anything. Also, I changed about 6 tcpip.sys files but there were only 2 on the CD.
I also tried winsockfix and some netsh commands (along with this program http://support.microsoft.com/kb/299357
which didn't do anything.
