Running Windows Server's 2012 R2 with all the latest updates. All of these servers in question are terminal servers. The number off users on these terminal servers are very low, between 3 and 12 users. The servers are virtual on VMware platform. From time to time the users experience that that the file explorer window close. I checked the Event Viewer right after a user reported the problem, but I could not find any items in the log that would indicate any related problem.
Anyone have a clue about what this problem can be?
