Yesterday morning I started work as usual as ran into a problem mounting one of the shares from my XP PRO machine on my Macbook Pro. Obviously the first question I asked was WTF? Everything worked yesterday, and not today.
I did some Googling and found mention about opening some UDP ports, but my TCP/IP settings currently has all ports open, so that didn’t help. Then just for giggles I decided to turn off simple file sharing. That fixed it!
So if you receive the message “A volume failed to mount”, and then another one with “Error code -6602″ in it, you should check your PC’s file sharing settings. You would do this by following these steps.
How to disable simple file sharing on XP
- Open Windows Explorer ( Win+E or double click My Computer )
- Click Tools > Folder Options
- Click the View Tab
- Scroll down to the bottom, and uncheck “Use simple file sharing (Recommended)”
- Then retry mounting the share on OSX
- The operation could not be completed. ( Error code -6602 )
