Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I have SBS 2008 and the LAN is using a 10.1.1.0/24 subnet. The server has an IP of 10.1.1.2/24 and the clients are on a DHCP range of 10.1.1.10-254/24.

When I open Network Connections (ncpa.cpl), right click the LAN adapter and go to Status, it says the server IP is 10.1.1.2.

However if I go into the adapter and click into the IPv4 settings, it says:

IP:      192.168.0.2
Subnet:  255.255.255.0
Gateway: 10.1.1.5
DNS:     10.1.1.2

If I go into the advanced settings, I can see 2 IP addresses but only the one Gateway and DNS. If I remove the 192.168.0.2 address, SBS prompts for a reboot. After the reboot, the 192.168.0.2 address is still there.

Any idea why this is happening?

The TCP/IP stack might be corrupted and the solution could be to reset it. This Microsoft KB article

How to reset Internet Protocol (TCP/IP)

explains how to do this.

Essentially, you'll have to execute the following command in a command prompt:

netsh int ip reset c:\resetlog.txt

Reboot the server and re-configure the IP address.

If you have other network cards/configurations, make sure you jot down the addresses, subnet masks etc. before you reset the TCP/IP stack.

Thanks I'll give this a go this weekend when we're able to have some downtime. –  Reado Aug 12 '10 at 22:31

Rerun the "Connect to the internet" wizard. You'll find it as the second task in the SBS Console.
