Hello David Graham:
Thank you for posting.
If possible, can you open activity monitor on the old Mac Mini and verify that none of the FileMaker Server processes are running. The path for Activity Monitor is Applications > Utilities > Activity Monitor.
In Activity Monitor you should be able to show all processes and filter by "fm" to get the FileMaker Server processes. If no processes are present, reboot the old Mac mini and also power cycle your router. Once the mini is back running verify that no FileMaker Server processes started back up.
If you do see processes running in Activity Monitor, you will want to run the uninstaller included in the FileMaker Server installer again after stopping the processes.
Let me know if you have any further issues.
There are no “fm” processes appearing in activity monitor. I looked there before when the server was still installed, not running butstill causing trouble, and I couldn’t see anything I recognized as filemaker related either, but I may have missed an fm hiding in there somewhere.
Both minis have had their power cycled, but I did it again on the serverless mini, and it looks like that did the trick – it is not appearing
on the list of servers. Hopefully its ghost is really gone <g>.
