I have a SBS2003 server with everything working fine. It has a motherboard with dual NICs, both working. The server is set up to use only one, and the other has been disabled since the last network config.
Today I noticed the NIC in use is 10/100, while the disabled one is 10/100/1000. I would like to switch operations, so that the server uses the gigabit port instead.
I did this on a non-sbs server by changing the IP address of the second NIC to exactly match the first, ignore the errors, swap the cable, reboot and everything is fine.
Not so in SBS. I tried that and while the server could still get online, everyone else on the network lost all services from dhcp to email. So, what have I done wrong?
What is the proper procedure to SWITCH NICs in SBS2003?
