I have 3 laptops and 2 NUC'S connected to my home network. Somehow i must have unknowingly turned on presentation on the only computer that is some distance away. It wasn't originally turned on but now its displayed in Computers and Contacts and I can't seem to find any answer how to turn it off. I don't need it, this is a private network not a business. All computers except the most distant one is Linux, only one is Windows. Anyone have a suggestion? Thanks, any help is greatly appreciated.
