I had the same problem, a workaround is to use the "subst" command in a script that replaces the shortcut for the program in VB something like this: set objShell = WScript.CreateObject("Wscript.Shell") sCommand = "subst N: ""\\server_location_of_network_drive_for_user""" objShell.run sCommand, 0, true This seems to fool Lightroom into accepting the location as valid for the catalog folder. It does show as a disconnected network drive which can confuse users but it avoids having to mess about with new locations\drives\external media and the like. We haven't had any major issues using it like this but YMMV since it is specifically against Adobe advice to run it on a network share.

I do remember in magicnet pro that the scheduling of the screen items can be a bit painful so you might want to check that.

We have some Samsung digital signage and magicnet pro running and it can be done since I have a screen running a powerpoint on a loop. I don't remember doing anything clever, when I publish the file the viewer starts up on its own and displays the .ppt

You might be able to do something with DNS by removing any forwarders and root hints from a specifically configured DNS server and using DHCP to direct all the computers you want to not have internet access to that server as their DNS. I haven't tried this but in theory it should work.
