You’ll struggle on here, this is log for v3 right?
Most on here have never even looked at v3 yet alone used.
Your using Windows 7 why don’t you up date to at least V4 if not v5?

Did you mess with source code? If so there is not much we can do.

Very Simple

Just delete the contents of this directory

C:\Users\apps\AppData\Local\Samba\
