Chuck: Changed IP address on a server? Very not good. Is it possible that, after the outage, the server rebooted and assigned it a default IP address? I've seen some hosts using a 74.x address if it can't get one from the DHCP server but that changes as soon as it can communicate with the DHCP server.
"DHCP with manual address" is an option I've never used - if you're assigning the IP address manually then what else is the DHCP providing? For computers that need a persistent IP address, I assign values manually. The IP address assigned outside of the range of IP addresses reserved for the DHCP server. For DNS, if there's not one on the LAN, I use 8.8.8.8 and 8.8.4.4. -- Douglas von Roeder 949-910-4084 On Wed, Jun 3, 2020 at 11:37 AM Chuck Miller via 4D_Tech < 4d_tech@lists.4d.com> wrote: > Hi All, > > We have a built Client server v 16.x running on a MAC > > Network set up is > DHCP with manual address > > This has been working till about 6n months ago. > > The hospital seems to test power outages on fairly regular basis.
