GPO Settings Display
I work in different schools over different days, and a recurring problem i've found is in Group Policy Management. When trying to view the settings for an existing group policy object, instead of displaying the settings it just displays "An error occured while generating report: An unknown error occurred while the HTML report was being created."
This makes it a long, time consuming task to go through every setting to figure out what the policy does. When trying to copy the object, the copy has the same issue.
