We've had the practice of setting up desktop shortcuts to network shares.
Because of some mysterious failed logons to the shares, I got to investigating the shortcuts.
This is in a domain-joined workstation.
I notice that we can examine the Properties of the shortcut and that there is a Security tab.
The security tab gives Full Control to:
SYSTEM
[domain username] for the current logon / matches the Desktop contents of course...
Local Administrators
And the Allow column is grayed out while the Deny column isn't.
Now, the actual network share has Security settings giving Full Control to a domain Group.
So, where do these particular permissions that we see in the shortcut come from?
