I have an issue with a Windows 7 64 bit machine...brand new out of the box, where it will not pull an ip address.

the command 'ipconfig' produces absolutely no output.

what led up to this was that I was trying to push Kapersky antivirus client from a server onto this machine. It installed, but I realized that I installed endpoint protection where I just needed the anitvirus client. I uninstalled Endpoint protection and upon reboot...no ip.

So far, the troubleshooting steps I have take are listed here:

This is the only machine in the network that can't pull an IP.

When I go to Network Connections, there are none (no LAN connection)

When I go to the device manager, the NIC drivers are there, but there is a message that they are not working due to 'misconfiguration'.

Seems like the IP stack is forked..hence my attempts with resetting it in the aforementioned microsoft support link.

From an Eleveted Command Prompt , type the following, in this order, pressing enter after each line :

ipconfig /flushdns
ipconfig /release
ipconfig /renew
netsh winsock reset

Always worth a try -

When I go to the device manager, the NIC drivers are there, but there is a message that they are not working due to 'misconfiguration'.

This could (maybe) be resolved with a sfc /scannow from an Eleveted Command Prompt also -

Is the Internet card and its (former) settings all from the first install, and not added extras ??

EDIT - The install discs are not usually required for SFC on Win7 systems

Tried all of the above plus I also tried lspfix.exe....no go.

I still have the media and instead of spending more time with it, I just did a reinstall.

Thanks for the above assistance.
