At work I have always accessed the shared files located on the main PC computer's "C" drive from my Mac. We recently updated all the PC machines to Windows 7 and now we can not connect either my Macbook or our iMac to the shared network but all the other Windows computers are still able to connect and access the files. The main office computer (containing the shared files) along with the three other PC computers in the office used to automatically show up in my Finder window's sidebar under "SHARED" but now none of them are automatically detected. If I use Command+K and search for the Windows computer on the network I can find it, but when I click the "C" file it tells me "You do not have permission to access the server 'Dave-Office'" or "The operation cant be completed because the original item for 'C' cant be found." Which doesn't make sense because I know the file is there and functioning because the other Windows machines are currently accessing it fine.

I don't think it can be anything to do with my Mac because I haven't changed any settings, the only difference is that the computer doing the sharing was updated to Windows 7 from XP. I never had to do any configuring before to connect to the files, I simply logged into our office's internet/network and was able to access the "C" file immediately as a Guest. So I have no idea why I'm having such a hard time connecing now. 

The "C" file is set to share with everyone and allow access by anyone on the network (which is set to Work Network). However, "Home Group" is also turned on. Could it be overriding the settings? I've tried troubleshooting and still don't have a solution.

Any suggestions are welcomed!

Hi JDudman,
