I have two computers - one with Linux Mint 18.2 (Sonya), and one with Elementary OS 0.4.1 (Loki). The Mint computer has a shared hard drive, and it has Samba installed to make the drive shareable on the network. When I installed Elementary OS a couple of weeks ago, I was able to access the shared drive by clicking on "Entire Network" in file manager. I then saw the Mint computer, clicked on it, and saw the shared folder. I then had full access to the shared folder from my Elementary OS computer. I have continued to have access till a couple of days ago, when we had a power failure at the house. When the power came back on, my Elementary OS could see the Mint computer, but could no longer see the shared folder: "Unable to Mount Folder -- Could not connect to the server for this folder. Failed to mount Windows share; No such file or directory".
Is there perhaps a file or two that got corrupted when the power went off and the computer went off at that point?
