Mapped S: drive unavailable because the file-share VM was unresponsive
The S: drive could not be accessed because the virtual machine hosting the shared folder was online but unresponsive. Rebooting that VM and the dependent terminal server VM restored access to the drive.
Killed once by someone from XL.net, on 2025-11-21.
What you see
- S: drive is unavailable or cannot be opened
- The shared folder behind the mapped drive does not respond
Why it happens
Likely Likely the virtual machine hosting the shared folder became unresponsive, blocking access to the mapped S: drive; a dependent terminal server VM also could not reach it until both were rebooted.
When it shows up
A mapped S: drive points to a shared folder on a virtual machine and the drive becomes unavailable even though the host VM appears online.
You are in this case if:
- The VM hosting the share is powered on but unresponsive to access attempts
- The mapped drive fails on more than one machine until the backend VM is rebooted
