My SD backup was to a blank Mac mini which boots fine. I made the mistake of starting the mini, on the network whilst the source of the backup was still there also. The result was I now see Myhost and Myhost(2) on my network even when Myhost isn't attached to the network.
The problem is, server manager won't open my server and I can't convince Myhost(2) it should really just be Myhost.
Thanks in advance to those wiser than me
I haven't lost my marbles, I just can't remember where I left them
