Windows 7 - Invalid IP Config error

I just upgrade from bulid 7000 to build 7057. when i try to connect to the internet it gets connected but when i try to surf no page loads. when i clicked on diagonise problem it says my comp doesnt have a valid ip config, wat do i do

How did you connect to the internet before? Ethernet wire? Wirelessly? Telephone line? At first blush, I'd suspect that switching to a different dialup number would help.

Ethernet. It worked properly with build 7000. N some times it doesnt detect any problem but still doesnt open any web pages

now the ip error is gone automatcally, but theres a new error "the remote device or resource wont accept the connection"

never upgrade first of all, from beta to beta. You'd get better odds at a casino.... and especially if nothing is broken... dont try and "fix" it

this is a known issue.... with your assuming 57 build... more commonly after an upgrade

hey problem solved just uninstalled my antivirus, and internet works now

yes, this WOULD be a problem. Even most games and applications will suggest that you atleast disable your AV during install... rarely did this ever mess things up, but does happen

This should be a last ditch attempt providing your ethernet conection is working (tries to connect but returns "invalid Ip")

Caution with registry modifications!

Disconnect your system from the net, and then run REGEDIT

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Inter faces
the JPG attachment shows the Paramater\Interfaces (specifically on mine, yours will be different)

EXPLORE each one of them, delete the ip info and replace with 0 info.

1. DhcpDefaultGateway
2. DhcpIpAddress
3. DhcpNameServer
4. DhcpServer

Then modify these resetting them to zero also

1. Lease
2. LeaseObtainTime
3. LeaseTerminatesTime

set EnableDHCP=1 & EnableDeadGWDetect=0

reboot the system and after the disk quiets down, plug-in the ethernet cable.
