Just to clarify I note that the IP address of the Master is now 192.168.0.5 whereas in the Server on Mini 3 there is a instance classed as 192.168.0.6 that is also connected but it really isn't.
Here is a list of IP addresses quoted by WakeOnLan.

Notice the multiple entries as it doesn't forget previous addresses until you rescan:

Thus the occasional need to reset the instances. Sometimes you will get an instance load with all the correct Instrument names for another computer but of course it hasn't got the licence or samples available on that machine. Eg tonight after my Master reboot I got the instruments for Woodwind appear on the Mac Pro whereas they are really on MINI 5. You can see from the Top List above that at one stage MINI 5 was 192.168.0.5 but that number is now allocated to the Mac Pro. Stuart
