Looks like the old server has died for some reason. It’s up and responding to pings, but unresponsive in any other manner.
I discovered this when DNS stopped resolving today. Whoops.
Luckily I had already installed DNS on the new server and I just had to move the NAT on my firewall.
But the home network is still pulling DNS, DHCP and print services from the old server.
Looks like I have some work to do tonight…
