RD is running on server, can't access it remotely?

send the unix command
ps -agx

make sure the display all output box is checked. When the output comes back look for somthing like

401 ?? S 0:38.32 /Applications/Remote Desktop.app/Contents/MacOS/Rem

Then send the kill command

kill 401

Replace the number from the line above. With the number from the output. After that control the server and launch Remote Desktop. Then make sure you set the preference to allow control when Remote Desktop is running.

If you can get into your server through SSH, I think you can shut down the Remote Desktop adminstrator through the "killall" command. I haven't done it, but the syntax should be something like

killall "Remote Desktop"

I don't know if you need the sudo in front of that or not.

Hope this helps.

You can't control but you should still be able to send a command from ARD. Log out the current user, which will quit the application.

Hope this helps! bill

I'm having this issue too.

I have a portforward to a fixed ip [internal] OSX server which runs the Remote Desktop admin software which I need to admin the LAN which i connect to from outside by using laptop form a variety of places and newtorks.
[Which is why I dont use a vpn to connect]

It's ok if - I connect to the server - then start up the Remote Admin - use it - and then remember to QUIT the admin ARD software running on the server before disconnecting ARD remotely.

If the Admin software is left running when you disconnect you cannot connect again to the server.

This seems like a major bug to me...

And very limiting if you have several people who need to connect remotely to admin the server and LAN for any reason.

There is a simple solution...
so obvious I missed it...

In the ARD admin preferences the is an option for
"Allow Control of this computer when Remote Desktop is active"
