Solution Steps
- 1 Press Windows key + R, type 'compmgmt.msc' and press Enter. Go to 'Shared Folders' → 'Sessions'. This shows all active network sessions. You can right-click any session and select 'Close Session' to free up a slot. This immediately reduces the session count.
- 2 Check if any devices are idle. Disconnect unused devices from your network or turn them off. This frees up sessions.
- 3 Increase the maximum number of sessions via registry. Press Windows key + R, type 'regedit' and press Enter. Navigate to HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters. Create a new DWORD (32-bit) value named 'MaxSessions' and set it to a higher number like 100 (decimal). Restart your PC. This allows more concurrent connections.
- 4 If you are using a home network, consider using a network-attached storage (NAS) device instead of sharing from your PC. This offloads the session handling.
- 5 Check for malware that might be creating many sessions. Run a full antivirus scan.
