Hi,
1.What is OS version of both client computer and target computer?
2.Is there any updates has been installed recently before the issue occurred?
3.Just bit confused about local terminal, is there any applications or program used for such function or you simply referred to console/local log into the computer?
4.For remote session related info, you could check event logs in both client and target PC to verify if any clues.
Event log checking:
TerminalServices-RemoteConnectionManager and TerminalServices-LocalSessionManager logs to view information about connections.
Step 1: Press Windows+R to open the Run dialog, enter eventvwr (or eventvwr.msc) and hit OK.
Step 2: Navigate to Event Viewer\ Applications and Services Logs\ Microsoft\ Windows\ TerminalServices-*
Hope this helps and please help to accept as Answer if the response is useful.
Thanks,
Jenny
