Windows 2008 Server NIC always adds static IP address of 0.0.0.0 in network config

networkingwindowswindows-server-2008

On a Windows 2008 server that is running under ESX 3.5 we see an issue for the NIC whereby it has multiple IP's. One is its normal IP 10.2.x.x, the other is the 0.0.0.0 address (subnet 0.0.0.0, gateway as per normal nic).

Heres the ipconfig /all dump

IPV6 is unselected in properties, and IPV4 is selected.

If I manually remove the 0.0.0.0 address it sticks until a reboot, then it reappears again when viewing the NIC properties.

I'm with Dave, I don't see the 0.0.0.0 that you're talking about.

You may, however, see a route to 0.0.0.0 in the route print command, which is the default gateway for your NIC. Your default gateway is where you go for access to any networks you don't know about.

Is this 0.0.0.0 address causing an actual problem?
