From memory:Any chance you could relate any changes you had to make to get it to work?
Run as Domain Administrator (or user with Administrator rights on both machines).
Enable File and Printer Sharing and Windows Management Instrumentation (WMI) for relevant subnet in Windows Firewall
Make sure Windows Management Instrumentation and Remote Registry services are running on the remote machine
Make sure Cumulative Update for Windows 10 Build 1511 KB3135173 is installed (this is what seemed to fix my 'The EventLog could not be accessed on xxx' error)
(Also make sure your antivirus software isn't blocking RemoteControl from installing TightVNC remotely)
I am able to use RemoteControl to connect from Windows 10 to Windows 10. Let me know if still not working & I'll take another look.
