Symptoms:

- My mapped drives have a red "x" on top of them and they either do or do not show the folders/files when clicked on

- My mapped drives are missing

- My mapped drives tell me they cannot be found


Cause:

Network disconnects, planned auto-disconnects, and just not restarting your computer enough can cause these issues to arise.


Solution:

- Try logging into login.microsoftonline.com in Internet Explorer. Once that loads up, try accessing mapped drives again.

- Try logging off Windows and then back on again or best yet, try restarting your computer.

- Contact your administrator if it happens enough to see if any settings can be changed for your situation.
