Thank Eli,
I did a quick checked on services per your suggestion… they are all enabled. And Yes! I did the drive mapping and did the drag&drop files into the mapped folder.
One thing though, I am using switch, http://www.tp-link.com/en/products/details/?model=TL-SG108#spec, instead of router. Will this be a problem ? (i.e. I can’t do the forward setting you recommended in your blog).
