At first I had a Dell laptop and tried to set up VNC access; it would not connect. I brought my personal 2011 MacBook Pro in to work and connected it, still couldn't connect using VNC. Using Remote Desktop, I was able to add the computer and set my Pro as the administrator. I could see it fine, but could not connect. But I noticed that if it asked me for username and password, I could get it to work. If it just asked for a password, I could never connect. No matter what password I entered it would not function. "Authentication failed".
Rebooted the server, all of a sudden I could connect...for a while. After a while though, I would connect and be unable to do anything. I can see the menu change as I click between windows and the desktop so I know I'm connected. But none of the buttons or anything respond. I close the console window, and then attempt to reconnect, and get "Authentication failed".
So...fast forward. Company buys me a MacBook Pro at my request. I load up Apple Remote Desktop and set the work Pro as administrator for the Mac Mini Server, and redeploy the package. Can't connect. So I physically move the Mac Mini Server out to my desk and connect it to my secondary network drop; Apple Remote Desktop connects perfectly every time. We put it back in the server room and change the switch port so that while in the server room it's connected to the same port that it would be if it were at my desk. Connects fine...but then again, eventually it just drops and I get Authentication failed.
Now here's the thing:
- I can ping it. Which means it's not a connectivity issue.
- I can see it says "Online" in ARD, which means Apple Remote Desktop is functional on both the client and the server.
- I can issue commands to it. I can tell it to launch an app, restart, etc. which means ARD is functioning and authentication is actually successful.
Now, based on what I know of computers, it almost seems like the VNC sessions are getting "locked" somehow. As if it can't create a new session because there's already one there. Problem is I don't know if that's what is happening, or why, or what to do about it. I need to be able to view/control this server readily, which is part of why I bought Apple Remote Desktop in the first place. I don't have this issue on any of my home machines, which seems to tell me that the server OS might be the cause.
Long winded, yes. But does anyone have any suggestions?
