Are you trying to change the DNS servers or what are you trying to change? Can you give a sample of the command output you are trying?

Are you ssh'd in to the IP address of the controller or the DNS name? If the DNS name changes, it's possible that may be why. I'm not sure why as we don't have many details here. I'd almost think a video would be helpful. I'd almost wonder if there are any errors logged. Have you checked the EMS or messages file? (rdfile /etc/log/messages I believe or /etc/log/ems, may have to do ls on that directory to see it)
