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?
