Sync to Mac sometimes works, sometimes doesn't. Why?

[rbmjr]

I recently added a Mac to my PC network and set up several profiles to sync folders from my PC to this new Mac. Sometimes the profiles run, and sometimes they do not. What setting or other change do I need to make in the profile to have the profile work consistently.

The message I receive is "\\Mac.local\me\music\*.*: Unknown Error"

Followed by "Error scanning target folder."

It looks like this is a network error, could you try setting the "retry on network error" options, in ViceVersa -> profile settings -> network, it might be a temporary network error. thanks
