Last week I sat down to stream some TV to my tablet, and a warning popped up -- 'A computer on the network has changed your Homegroup password.' Very ominous. And of course I couldn't do anything until I had entered the new password. Which I didn't know.
I checked all the computers on the network, and they all gave the same warning, so obviously none of them had changed the password.
On an unrelated note, my daughter was staying at the time. Well, not really unrelated, because five years ago I gave her my laptop for uni, and obviously I had set up the initial homegroup way back then, and the laptop considered itself 'boss' of the homegroup, so felt entitled to reset the password to the original one when she fired it up. Which I had forgotten, or course, but it is easy enough to change once you know which machine is changing it.
So I'd really been 'hacked' by myself from 5 years ago. The moral is, don't panic, there's probably always a simple (!!) explanation.
