I'm currently running Lion Server on a Mac Pro 1.1 (which is why I haven't upgraded, because I can't). I have an iMac running Mavericks. The rest of my family use Windows 7. I have the iMac and the Server set up exactly the same for file sharing. I can access the iMac and it's files from my Win 7 machine BUT, not the server. I seem to recall there was some issue with Lion because Apple had changed SMB. I can't find anything indicating if the issue was resolved or if there's an upgrade to Lion's SMB protocols. I believe at the time it was recommended to go to a 3rd party SMB app ( DAVE?). Is that still my only option?
