Postup řešení
- 1 Press Win+R, type 'cmd', and press Ctrl+Shift+Enter to open Command Prompt as admin. Type 'query session' and press Enter. Look for sessions with the same ID. This is the collision. Note the session IDs.
- 2 For duplicate sessions, type 'logoff [sessionID]' for each duplicate, but keep one active. This resolves the collision by removing the extra session.
- 3 If the error is from a service, open Services (Win+R, services.msc). Find the service and check if it's set to start multiple instances. If so, change the startup type to 'Automatic' (not 'Automatic (Delayed Start)') to prevent overlapping starts.
- 4 Check the registry for session-related settings: Press Win+R, type 'regedit', and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server. Ensure 'TSEnabled' is set to 1 and 'fDenyTSConnections' is 0. This allows multiple sessions but avoids conflicts.
- 5 If the error persists, restart the computer to clear all sessions and start fresh.
