We have a Small Business Server 2008 which is running into a huge issue.
Two times now we have run into a situation where all users are having DNS failures causing the internet to not work.
After some investigation we found the server had managed to change its IP from 192.168.1.254 to 192.168.1.2
This has happened twice now.
Has anyone ever had this happen to them?
Its causing major down time.
Do you think it will be worth replicating the DNS on another one of our servers then pointing DHCP to that - although does this require the server being promoted to a Domain Controller?
