Actually really simple to set up – probably why there’s no help in the documentation!

0) For both Master and Client machines: In iTALC Management Console, Authentication -> Logon Settings, add permissions for ‘everyone’ in iTALC Server.

1) Install iTALC on Master computer, and just the service on your client machines.

2) For both Master and Client machines:  In iTALC Management Console, in Authentication, set up your public and private key base directories in a shared network directory, then Launch New Key File Assistant to generate authentication keys (I chose administrator) then save the keys in your shared network directory.

3) On Master Machine: Open iTALC, open ‘classroom manager’ on left of sidebar, richt click ‘Create classroom’, then add computers (use hostnames rather than ips if your router uses DHCP)

That’s it!  :-D
