Help with Apple Remote Desktop
Just to give a bit of background, I've recently completed the Apple desktop and server training courses to get the ACTC certification. This is because we've recently had an influx of Macs on our network here and nobody else wants to touch them!
Anyway, I am still relatively new to the world of Macs myself and realise I still have a lot to learn when it comes to putting theory into practice, that being the case, I've bee having trouble getting ARD to work properly, primarily with regard to deploying software updates.
Some background: we have 3 Xserves with Mac OSX Server 10.6.8. One is the main server and the other two are replicas. We use Active Directory to manage user accounts, with OD on the main Mac server administering preferences and services for the Mac clients.
We now have around 60 Mac client machines on our network, all of which currently run Snow Leopard as well. These Macs are all bound to OD and AD. However, for day-to-day administration, we have a Mac that sits in the main IT office and is on the same VLAN as the Macs (which are on a segregated portion of the network at this institution), and with the admin Mac, I can remotely VNC to the Mac servers as required.
Over the summer, we had a server rebuild and prior to that, ARD was used from the main Mac server to manage the client Macs, but since the original server build was set up by an external consultant who did not document properly, we couldn't find the original license information and ARD was left off the server post-rebild. As an alternative, a later version was deployed to the admin Mac (which is running Lion).
Now here's my problem. I can run ARD fine on the admin Mac, it detects all the Macs on the network (which I have grouped etc) and I can control their screens, but I cannot do any remote management with it whatsoever. For instance, when I try to deploy (much needed) software updates through ARD, it returns the following:
"Error: The operation couldn’t be completed. (NSURLErrorDomain error -1102.)"
The only way I can get updates to work is by logging directly to a client Mac and running it manually. When I try to do this through ARD, I get that error.
We have the software update service on the Mac server and a repository for storing them, and the clients and servers can update fine, but just not through ARD on this admin Mac. I suspect that since the admin might be having trouble accessing the software update repository on the server, but I'm really not sure. I've googled this issue quite a bit, but there seems to be very little information on this one error (typical) and the information I did find wasn't really relevant to my situation. I thought that maybe the Mac had to be directly bound to OD to be able to "see" the software update repository, but this hasn't worked either.
This is driving me up the wall; I just cannot understand what the problem is here and it's especially frustrating that I can find no information on this error message, even on Apple's own website. I would be grateful if anyone here could assist. As someone new to all things Mac, this one has me well and truly stumped.
