ARD 3.3.1 Can copy, send messages, but can't observe or control.

Hi,
I have the following setup:

Client: iMac with 10.5.8/ARD 3.3.1 at work
Admin: MacBook 10.6.1/ARD 3.3.1 at home

I'm trying to observe/control client machine over WAN, but can only copy and send messages. I can observe/control via LAN/wireless LAN. Remote management is enabled in sharing settings on client. Ports 3283 and 5900 (TCP/UDP) are forwarded and open. I can authenticate and see the status, current application, current user, Mac OS version. It seems to me there's some kind of problem with port 5900, but I can't figure out what the problem might be as this port is properly forwarded and is open. Firewall on client is opened to all incoming connections. I have spent almost a week trying to figure this one out with no luck( I've read this forum from top to bottom - still no solution.

Can anyone suggest anything in my case?

Thanks to all!

MacBook, Mac OS X (10.6.1), ARD 3.3.1

You might want to do a port scan of the client system (using the same IP address you're using in ARD) using Network Utility and confirm that 5900 is indeed open. That might point the way to a solution, or at least the next step in troubleshooting.

i have the opposite problem, i can take over and observe the machine, but i can't send messages, when i try and telnet to the machine via port 3283 it gets denied, but there is no firewall between the two of us.

oh also, on the remote host when i try to telnet on that port locally the connection is denied. and yes it has the most recent version of the ARD client.

Nick, I'd suggest you start a new topic with your issue (use the "Post a new topic" link at the top of each main topic page). It's generally better to ask a question as a new topic rather than as a reply in someone else's thread. It's more courteous to the original poster, and is more likely to get your question the attention it deserves.

Regards.

Are you running the Remote Desktop Administrator under an Administrator account?

If you are not logged in as an admin user look under Remote Desktop (menu)-> Preferences... ->Security tab. If the radio button for "Access restricted to the following features" is selected & you might not be allowed to do those features.

Options.
1. make your account an admin account (not recommended)
2. Log into the Remote Desktop admin computer as an administrative account & go back into the preferences -> security & either Select "Full access to all features" (what I do because the you need to know the username & password to the client computers & they can be set up to limit admins anyway) or enable the specific additional features needed for all users using the checkboxes.

I have found what was causing the problems for me. It was a third party firewall program called "NetBarrier" on my client iMac. I hadn't fully uninstalled this app the first time I tried that and, therefore, didn't think about it as being the cause. After fully uninstalling it and restarting my client machine everything works perfect.
