I have a mac mini server running OSX Lion 10.7.4  Until powring this down over the weekend, it had worked beautifully.  I coould connect, access shared files, screen share (as I am running in head less) as well as access it via Server Admin from a remote computer.


After restarting, I can still share files, but am unable to access the sceen share or administer remotely.  The odd thing is that when I connect it to my TV I can then also access it with screen share from another MacBook Pro as well as use server admin for remote admin.  As soon as I run it headless again, I cannot access it via screen share.


I have noticed that the screen share finction has changed from before, so am wondering if this has anything to do with it.


I have not chnaged any settings on it.  Firewall is the same as before, filesharing and screen sharing is enabled and I am trying to access it as a registered user.


Any help greatly appreciated.



Mac mini Server (Mid 2011), Mac OS X (10.7.4)

    I bet it's a DNS problem.

    In terminal type the following:


    sudo changeip -checkhostname


    What does the output say?


    Additionally, you could also try connecting by using the IP Address directly instead of the name of the computer.

    It probably looks like or or something like that.

    Yeah... Type the changeip thing on the servers terminal application.  It's in the Utilities Folder.


    There are so many variables to explain why it might work for filesharing.  For instance, if you're using a .local hostname, then the client will connect no problem.  There's a kerberos issue that comes into play when connecting to a file share that doesn't when using screen sharing.

    There's your problem.  DNS is 100% reliant on a stable network connection.  If you switch from ethernet to airport, it will break things!


    You should pick a connection type and stick with that permanently.  Remember, a server - even a home based one - is designed with high availability in mind.  A changing IP address of any kind on a server defeats this!


    The reason the DNS hostname is not available is that your DNS is pointing applepip.local to  NOT 0.14.


    You might get lucky and find that when you plug back into ethernet things will come back to life as they did before.

    Out of curiosity, are you connecting your server to the TV via the HDMI connector on your mac mini?

    Yep it could be.  I know that in lion they did some strange things with the way that screen sharing is configured.  VNC virtual displays etc. 

    Also, I know that a few months ago, there was an issue with the new mac mini and it's HDMI port.  Pretty sure they fixed it with a firmware upgrade a wihle back.  ...and it only affected a certain model.  If I recall the issue prevented any display from working....  Though I'm not 100% sure about that.


    Do you have the white HDMI to DVI adapter that came with the mac mini?  It's about 4 inches long. 

    I'm curious about whether or not you'll be able to connect with the computer with that plug inserted.  You don't have to connect a cable to this little white adapter...  Just plug it into the mini by itself.  It might be enough to trick the mini into thinking there's a display attached.
