Hello, few days ago I set up on iMac (Mountain Lion) access to Shared Folder which is on a PC laptop (Windows 7). Till yesterday it was working all fine. I could access the folder, read and write inside it. Now iMac can still see that PC but can't connect to it. When I try to do it it says "Connection Failed". I haven't change anything since it worked. Anyone has a clue what happened and how to fix it?
