Can't control Lion macmini with ARD 3.5.1 client

I am having the exact same problem with Lion Server and ARD Client 3.5.1. ARD is the only way I can connect to my Mac Mini Server. I believe there is something up with ARD 3.5.1 Client and the Admin. The only way I could get around it was to revert to a previous ARD Client like 3.4 or 3.5. But now since both ARD and Screen Sharing are down I cant connect to the Machine. Can anyone help?

When I reverted it did not work either. I all I get is a black screen on ARD client 3.4 now. Someone Please Help!

Lion/ARD users,

I am also having issues with ARD and Lion.

I have done my Lion upgrades remotely via ARD. The Lion upgrades do ok and after install reboot I get remote connection back up again. However after running software update, which downloads ARD Client 3.5.1 my Apple Remove Desktop is no longer able to connect to the machine.

I also cannot access machine via VNC but can access it via SSH.

So it appears to be a problem with VNC ...

Here is the error:

So while ARD see the "fritz" client ok it cannot connect to it.

I have looked in Console log and there are no clues there about what is causing the problem.

I have install the ARD Admin 3.5 Update, so that does not help fix the problem.

I have 7 remote Mac I need to access to this is a signficant problem...

Cheers,

Zebity.

Having very similar issue connecting Mac Book Pro to iMac. All software is updated on both machines, and still get a "Connection Failed To" message.

Sounds a little like my problem here:

So you have so machines that are fine, and just one that is not? My problem child is a macbook pro.

Same here ARD on Lion is unstable - some times it works and sometimes not. You can connect to a client and 5 Minutes later you cannot until you reboot your own machine and even then there is no guarantee. That is ridiculous.

Same here can't connect to brand new iMac running Lion

from a MBP running SL 10.6.8 with ARD 3.5.

Can connect fine to my servers (running SL)

Apple Remote Desktop User,

the solution is pretty simple.

Do not install the ARD 3.5.1 Client Update.

ARD 3.5 Admin appears to work fine.

I now have five machines all working with 3.5 Admin ok.

1 machine with 3.5.1 not working

I am not going to accept any of the Software Updates to move to ARD 3.5.1 until there is a clear fix to the problem.

I even remove all the various plist file under /Library/Application Support/Apple/Remote Desktop (which was suggested in another thread to address the problem) and had to reenter original installation serial number, but my connection to 3.5.1 client still does not work.

I cannot even do VNC to this machine that is not working with ARD.

i have also Problems i can see my machines are online but i canot connect to them they are all READY....

But when i try to control it and CLICK Control or View i get connection failed !!!!!

All maschines are on 3.5.1 and mac os x lion.....

any solutions`?``

Hmmm, how to go back on machine already updated? reinstall or TimeMachine seems to be my options. Strange one, ARD has been rock solid for many versions now.

hi coocoo

you mean to timemaschine back before LION?

It also broke standard screen sharing. I was using screen sharing on my MBP (Lion) to upgrade my Mac MINI to lion and after both did the ARD client upgrade, screen sharing refuses to work. Have changed the settings on both, tried remote management vs screen sharing, tried VNC, no joy. Says it's connected, but the screen sharing button doesn't even come up anymore. File sharing, great. Screen Sharing, toast.

Hi Folks,

I was having the same issue and was banging my head against the wall.

The fix seems to be pretty simple, it looks like if you go to the sharing preference pane on the client machine, and then uncheck and check again the Remote Management option the screen control feature comes back to life.

I hope this helps, it seems to have solved the issue on 2 of my client machines so far.

YOU ARE MY HERO!

this has solved the problem, i was calling to the store where the remote computer is located.

i told them to go and do that what you have say....

and see i can connect again.....

thank you very much....🙂

ssh into the offending machine and type:

sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/k ickstart -deactivate -configure -access -off

sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/k ickstart -activate -configure -access -on -restart -agent -privs -all
