Ok so this is how my network looks:
A'(saloon computer)<-----> B'(computer with tplink router)<----->C'(my computer)
A' and C' are each connected to B' through a 20 (give or take) meter cable. (not wireless). C' is windows 7 X64, A' and B' are win xp.
I just downloaded a 6 gig movie (C' computer), and when i try to copy it (or remove it) to B' computer, the copy process starts, then freezes, then i get an error (see attached file).
I even tried storing the movie in 200 megabyte rar archives, and copying them ONE BY ONE, but same error consists.
but this is the strangest thing: when copying the movie from C' to A', there are NO PROBLEMS WHATSOEVER!!!
