A shared drive stopped working

A missing drive letter, an “Access denied” message and an unreachable server point to different checks. Start by noting exactly what you see.

Start with these checks

  1. Confirm which share is affected

    Note the drive letter or share name and whether other shared locations still open. If your organisation has already given you an approved shortcut to the same share, check whether that also fails.

  2. Compare affected users and devices

    Ask whether a colleague who already has access can open the share. If you are working remotely, check your usual VPN or remote desktop connection. One person seeing “Access denied” gives the support team a different starting point from everyone losing access.

  3. Record recent changes

    Think about account, device or network changes that happened around the same time. Record the error and whether it affects opening files, saving changes or both. Share the symptom with your support contact before changing permissions.
