Based on recommendations, about a month ago I disabled Application Data redirection in Group Policy but didn't delete the Application Data folders from the server.
Over the weekend, I ran a script that removed them.
This morning, CRAZY things are happening.
For starters, all icons pinned to the taskbar won't work. You can remove them.. and add them back (which most of our users won't know how to do).
So far it doesn't seem like anything tragic... but is there an easier way to fix this that any of you are aware of?
