So I ran across this error recently. We use Microsoft’s AD product for server and have several drive that get mapped when we log in. A user was getting this error.
Turns out this is an issue when you have those mapped drives. If you go to My Computer, check to see if the network drives show as disconnected. If they do, that’s usually the cause of this issue. Double click those network drive and see if this error message stops showing up. I’ll bet it does. Now, it you continue to have this issue, there are other issues with those drives not staying connected you need to check out. That’s for another day….
