I run an in-home network of 4 computers and also connect to my handicapped sons two computers about 200 ks away.
On my internal network 1 computer runs Linux, 2 run Windows 10, and 1 runs Windows 7. The contacts lists have vanished on all of them.
After adding his second computer yesterday, my contacts list vanished and has instead been replaced by his single new computer called Danny 2.
I have tried to make a new contacts list up, but so far I have been unable to do anything.
Have I done something wrong or what?
