When in a remote session over Terminal Services/Remote Desktop, the yellow bar at the top of the screen displays an image of a lock (tooltip says: Security Details) in addition to the usual push-pin, host name and window size controls. Older versions of Remote Desktop didn't have the lock icon.
When the lock icon is clicked the following message is displayed:
"The identity of the remote computer was verified using Kerberos."
I don't understand the reasoning behind this or why it's important. Under what circumstance has a problem occurred in which this lock icon could have provided a solution?
