I am running Mac Pro with 10.8.2 installed. My HTPC is running Windows 7 and need to access Mac Pro HDDs. Everything works fine until Mac Pro is switched off or restarted. Then I have to open sharing preferences, click option, untick and re-check SMB sharing in order for Windows 7 to be able to access them. Otherwise Windows ask for a password which there is none. Even if I set one it doesn't help either. Any solution?
