At this point I am trying only to be able to log into my own desktop from my laptop at any location. The desktop was set up to go to sleep after a period of inactivity. Am i correct in thinking I have to set it to go to sleep "never" in order to be able to contact it from a remote location?
Also, it seems to me to generate a new password for the desktop, every time it is rebooted. Is that in fact what is happening? If so I have to use a new logn PW every time the desktop gets restarted - which might be every few days. Is this correct? And is there a way to bypass this without compromising security?
