Hello, I had a problem using remote desktop utilities like vnc, logmein, etc. I could log in in my local lan but when I was away it didn't work. I thought about having someone to press any key on the keyboard to wake up the monitor and guess what, it worked! I could login remotely. I only use display sleep after some minutes, can this cause the problem? Computer sleep is set to never. Anyway I would like to share my experience because I have seen a lot of people having trouble to use vnc. Do I have to disable anything else ? But why Display sleep doesn't allow remote login? However when the display sleep is activated I can ping my mac mini server.
