Having an issue with freepbx failing to work after turning off our a server that used to be a domain controller.
I have switched the DNS settings on the freepbx side to the correct DNS entries, but every time we down the old domain controller, all calls just quits. I’m not sure where to start on this. Probably not even DNS related, but I don’t know what could be running on the old server that would make freepbx quit working when shutting it down.
Background, we inherited this setup from a previous admin who is no longer with the company so… yea…
Any ideas on where to start/look? We did a packet capture on freepbx’s server network port, and we saw it try to hit an old DNS one time, but couldn’t duplicate it. (which is why we thought it might be DNS related). What are some main services that would be ran on another server other than itself? I can take that and cross check everything.
