Shelving need proper permission - better hand out this permission where required using standard methods instead of adding LogOver to the equation.
Starting with Microsoft Windows 8, LogOver which is based on the Microsoft Windows security privilege Impersonate a client after authentication now additionally also requires elevation.
The new method of automatic start of workplace seen in 800xA 6.0 and onwards addresses that w/o causing Microsoft Windows to ask for user credentials at every workplace start.
I have written about this on AKS in past articles.
Hints:
- Scheduled Task
- Run task with highest permission
